BLOOD ALCOHOL SCIENCE

 

Blood alcohol content", "blood alcohol concentration", or "blood ethanol concentration", or "Blood Alcohol Level" (BAC) is the concentration of alcohol in a person's blood. It is usually expressed as a fractional percentage in terms of volume of alcohol per liter of blood in the body. That is commonly expressed without units, or as a decimal with 2-3 significant digits followed by a percentage sign, which means 1/100 of the previous number (e.g., 0.0008 expressed as a percentage = 0.08%). Each country or state may define BAC differently.

 


Since measurement must be accurate and inexpensive, several measurement techniques are used as proxies to approximate the true parts per million measure. Some of the most common are listed here: (1) Mass of alcohol per volume of exhaled breath (e.g. 0.38 mg/L), (2) Mass per volume of blood in the body (e.g.: 0.08 g/dL), and (3) Mass of alcohol per mass of the body (e.g.: 0.0013 g/Kg).
The number of drinks consumed is often a poor measure of blood alcohol content, largely because of variations in weight, sex and body fat.


An ethanol level of 0.10% is equal to 22 mmol/l or 100 mg/dl of blood alcohol.[2][3] This same 0.10% BAC also equates to 0.10 g/dL of blood alcohol or 0.10 g/210L of exhaled breath alcohol or 0.476 mg/L of exhaled breath alcohol. Likewise, 0.10 mg/L of exhaled breath alcohol converts to 0.02% BAC, 0.022 g/dL of blood alcohol or 0.022 g/210L of exhaled breath alcohol. You can learn more here.
