How do you convert ethanol to BAC?

How Do I Convert between BAC, mmol/L, and g/dL?

  1. 1 mmol of ethanol per 1 L of blood = 4.61 mg of ethanol per 100 mL (i.e. – 100mg/dL, per decilitre, or one tenth of a litre) of blood.
  2. 100 mg/dL = 0.10 (g/dL) BAC, or 0.10%. ( i.e. — divide by 1000 to get the BAC)
  3. To convert from BAC to mmol/L, ([BAC]*1000)/4.61 = mmol/L.
