It allows mixing not only the water with alcohol but use it for other fluids containing alcohol. To determine the solution with clean water, it is necessary to enter a zero in the column for the one liquids' volume concentration. Details of calculation and a bit of theory and history can be found just below the calculator:.

In the 19th century, at least one-third of the Russian Empire's budget was excise taxes on alcoholic beverages. The excise tax is calculated depending on the strength of the drink amount of pure alcohol. Therefore, the task of determining the amount of pure alcohol was at the level of national importance. As long as this topic was not connected to science, beverage strength was determined with interesting methods. The way of proving the quality of Polugar was simple - set it on fire, and it will burn until half of its amount burns out.

Obviously, burning alcohol to determine its strength is not convenient, so the next step in the Russian history of the vodka industry was to borrow the Western experience: determine the amount of alcohol with areometers alcoholmeters - the devices to determine the content of alcohol—they were already extensively used in the leading Western countries.

Alcoholmeters of the 19th century created for use in Western countries' mild climate gave poor results in Russian temperatures. Besides, there were different methods of measuring the volume and strength of alcohol. These premises served as an incentive to activate the domestic science in the studies of alcohols' solution properties. Mendeleev held a serious study of aqueous-alcoholic solutions.

While working on his doctoral dissertation, Mendeleev studied the change of the alcohol solution's specific mass with the concentration and temperature. The volume density of the aqueous alcohol solution and any other fluid is temperature-dependent. The density of the solution decreases with an increase in temperature the volume increases.

The change is not linear, as well as water density's behavior with the temperature change. It also appears that the solution density nonlinearly varies with the alcohol concentration change. Surprisingly, the volume of water and alcohol separately is almost always greater than the solution obtained by mixing these components.

Blood Alcohol Content (BAC) Calculator

The reduction of the volume of aqueous-alcohol solution, now known as contraction, reaches its maximum when the alcohol concentration in the solution is 50 to 60 percent by weight, see. A clear pattern in the change of the volume has not been identified.

Instead, Mendeleev created the approximate formulas used to create the tables of density dependence of alcohol solutions of mass or volume concentration and the temperature.Use our concentrate calculator.

Reference: European Pharmacopoeia 7.This blood alcohol concentration BAC calculator is digitally designed to determine both blood alcohol content and how long alcohol stays in your system.

BAC is typically reported as a percentage such as 0. It is also referred to as blood alcohol content and blood alcohol level. This unit quickly computes approximately what it might be at the end of a drinking session.

It also estimates the time it could take to metabolize that level to zero. The answers should not be taken as absolute, as every person is different. Click on the graphic image icon and fill-in these questions:. The results will be displayed as the estimate at the end of drinking, and the approximate time it might go down to 0.

The formula used is a procedure provided courtesy of Herbert Moskowitz, Ph. Once it is computed based on the above variables, the percentage of alcohol metabolized during drinking time is subtracted. There are other aspects; age, tolerance, and physical fitness. These variabilities could produce a small fraction of error in the final answer.

Here is how they might affect the outcome of our formulation. Age : Younger people have a higher proportion of body water as a fraction of their total weight, and older people have less. So, a younger person may potentially have a lower rate than an older person. Physical Fitness : Individuals who may be overweight may have a smaller proportion of their body weight than water. Lean people tend to have a larger fraction of their body weight than water.

Therefore, overweight people could have a lower than our formula indicates. Tolerance : A regular drinker will have a higher tolerance for metabolizing alcohol than someone who is not.

Medical Advice Disclaimer.Data for the density of ethanol-water mixtures is very widely used in industry and several methods of storing and presenting this data are used, each with its own advantages and disadvantages.

The most flexible, powerful and accurate method is to use an ethanol density calculator application like AlcoDens. This allows the density to be calculated as a function of both the strength and temperature of the mixture. AlcoDens can also be used in reverse mode, i. The strength or concentration of an ethanol-water mixture can be expressed in several different ways. This screenshot shows the AlcoDens ethanol density calculator in action.

It can calculate the density for a known strength, or determine the strength for a known density. Click on the "Home" option in the menu above to get more details on AlcoDens and to download a free trial copy. The relationship between ethanol density and strength can also be shown on a graph see below. An advantage of using a graphical representation is that the "big picture" behavior is seen very easily.

This non-linearity is caused by the shrinkage that occurs when ethanol and water are mixed. The non-linearity is not obvious when using a computer program or tabulated data to determine the ethanol density, even though the density vs composition behavior is accurately represented.

Unfortunately the graphical method of representing the ethanol density has several disadvantages. Unless the graph is very big it is impossible to read the data accurately. Multiple temperatures can be accommodated by drawing more than one curve on each graph, but this results in interpolation being required for values between the displayed temperatures. Plotting a graph makes the non-linear relationship between ethanol density and strength obvious.

This non-linearity is the reason for the inaccuracy of simple proportion-based methods for ethanol blending calculations eg Pearson's Square. Another alternative for presenting ethanol density data is to use a table. A small excerpt from such a table is shown below. A table allows the ethanol density data to be given with much greater precision than when shown in a graph.

The disadvantage of tables of density data is that huge tables are required to cover the practical ranges of temperatures, concentrations and ethanol densities with sufficient accuracy. This results in book-sized publications like the Practical Alcohol Tables or else partial tables like the American TTB Tables which give full accuracy at only one temperature and then require correction factors to be applied for other temperatures.

Tables of ethanol density have the same disadvantage as graphs in that they usually include only one set of units. In order to cover other sets of units for the density and strength data the entire table has to be reproduced. In times gone by, detailed tables of ethanol density were the only way to achieve sufficient accuracy to satisfy trade and tax regulations. Fortunately we now have computer programs like AlcoDens that allow us to easily achieve the required accuracy.

Tables of ethanol density data achieve high precision at the published combinations of strength and temperature. But in order to achieve similar precision between the published points it is necessary for the tables to include very closely spaced data points so that simple interpolation methods remain accurate. This results in tables that are useably accurate being very large. Note that the example given here is a small extract only.

Ethanol density data is frequently used in the alcoholic beverage and industrial chemical industries. The most common use of this data is in determining the strength of ethanol-water mixtures. Measuring the density of the ethanol sample is much quicker, and requires much less expensive equipment, than using chromatographs or wet chemistry methods and the measured density is easily converted to a strength.

Knowing the relationship between ethanol density and strength also allows conversion between the different methods of expressing the strength of ethanol-water blends.

This allows the impurities to be removed efficiently, but the product cannot be consumed at these high concentrations and it is necessary to dilute the ethanol down to a safe level. In most countries the tax on potable ethanol is at least an order of magnitude higher than the production cost of the ethanol and this makes it very important to be able to blend the high strength spirit very accurately with water - you don't want to be caught cheating the tax man, but you also don't want to pay him more than his share.

As was shown above where the ethanol density data was presented as a graph, the relationship between ethanol density and strength is not linear. This greatly complicates the blending calculations and they can only be done properly if accurate ethanol density data is available. When less accurate methods are used it results in time-consuming trial and error methods being used to achieve the correct blend strength.

Although the basic hydrometer was invented about years ago it is still used in many distilleries and laboratories around the world.If you have a substance and you want to quickly convert the percentage of concentration to molarityour tool does so in three simple steps.

Alcohol products are generally labeled with a stated alcohol Proof.

Pycnometers are not as accurate as other methods, are very time consuming, and require well trained laboratory personnel. Results are generally not very reproducible and prone to much human error. Difficulties in measuring alcohol concentration with a Pycnometer includes reading the measurements by eye and holding temperature at a consistent and accurate level.

The need for considerable human judgment with visual readings leaves this method as being far to inconsistent and inaccurate to meet TTB labeling and taxation requirements. Hydrometers are much less accurate then a modern highly accurate Density Meter or pycnometers. While hydrometers are reasonably easy to use, they require very large samples sizes between to ml per measurement and often need off-site calibration. User error is a significant problem with measurements made by eye and temperature control is also a difficulty.

Significant time can needed to accurately bring and hold samples at temperature and again temperature levels are gauged by the users eyes. An additional issue is of concern with pycnometers and hydrometers as the alcohol measurement results are difficult to validate and document.

Traceability back to sample temperature at the time of measurement and calibration are difficult. While many methods may be acceptable to the US TTB they are of little value if user error causes an inaccurate reading.

In a shelf-pull or audit all that matters is accuracy in reporting alcohol by volume. The measurement is fast, accurate, and highly reproducible. Measuring Alcohol Concentration requires minimal Operator training using the DDM Plus Density Meter as the most common error of bubbles in the sample has been eliminated.

Alcohol measurements require very high precision and the presence of even the very smallest of bubbles will alter that precision greatly. The U-Tube that contains the sample is clearly displayed at X magnification so the operator can clearly see even the smallest bubble. The operator can view the U-Tube while loading the sample then magnify the view up to 10X if needed.

In addition the user may use the scanning feature to examine the entire U-Tube before measuring. The DDM Plus is loaded for measurements by injecting a small 1 ml to 2 ml sample with a syringe. The measurement results are displayed on the large The results may also be sent to any networked printer and can be used to generate a certificate of analysis, with your logo. Sample identification may be input manually or by the use of a bar code scanner or accessory keyboard.
