Blood alcohol calculator
Rough estimate from drinks and weight.
How it’s worked out
Never use this to decide whether to drive. Your real level can be far higher, and alcohol impairs driving below the limit too. If you drank, don’t drive. Method: the Widmark formula with a BMI-based factor and elimination of 14.8 mg per 100 mL an hour (Searle, 2015). Limits: Israeli Traffic Regulations 169A and Traffic Ordinance section 64B.
