Blood alcohol and breath alcohol unit converter

When it comes to converting alcohol units of measurement, the task is not an easy one due to the fact that some countries have different Breath to Blood Ratio. Our conversion tool allows you to easily and quickly convert alcohol measures in blood or air, depending on the BBR of the country.

This converter is also intended for professionals who calibrate breathalyzers. Indeed, when you calibrate breathalyzers, you have to indicate the reference concentration of the alcohol solution you use. Depending on the unit of the solution (mg/L, %BAC etc.) and the units used in the calibration software, you may need to convert the data.
