Terms of use

By using this site you accept the following.

The figures are estimates

Everything this site calculates comes from a published model of an average body. It is not a measurement of you. Real blood alcohol differs from the estimate, often by a wide margin, and it can be higher than the figure shown.

Not a basis for driving

Nothing here may be used to decide whether you are fit to drive, to operate machinery, or to do anything else where alcohol matters. The only level that is safe for driving is 0.00. We accept no liability for any decision taken on the basis of a figure from this site.

Not professional advice

This site gives neither medical nor legal advice. The legal limits are published as information, each with its source, and they can change at any time; the authoritative text is always the one at the source link, not our summary of it.

Availability and changes

The site is provided as it is, with no promise that it is available or free of error. We may change or remove any page at any time.
