Calculator: Blood ethanol concentration estimation

Calculator: Blood ethanol concentration estimation

Volume ingested  
Concentration ingested  

Important: Inputs must be complete to perform calculation.

Blood ethanol concentration  
Decimal precision  



  • 0.8 g/mL is the specific gravity of ethanol and 0.6 is the volume of distribution of ethanol.
  • In the United States (US), percent ethanol of beverages is proof/2 while in the United Kingdom (UK) and Australia, percent ethanol of beverages is proof/1.75.
  • For example, 80 proof vodka is 40 percent ethanol in the US, but is 46 percent ethanol in the UK or Australia. Use the pull-down unit selector to choose the appropriate Concentration ingested unit.
  • A swallow in a toddler is about 5 mL (1 teaspoon).

*Typical content for beer, wine, and liquor is 5, 14, and 40 percent, respectively.


Equations used
Blood_ethanol_concentration = (Volume_ingested * Concentration_ingested * 0.8) / (Weight * 0.6)

Only digits 0 to 9 and a single decimal point (".") are acceptable as numeric inputs. Attempted input of other characters into a numeric field may lead to an incorrect result.
