The unit of measurement cited refers to the concentration of ethanol (alcohol) by molecular count.
If an ethanol level of 0.10% is equal to 22 mmol/l or 100 mg/dl, then 1 mmol/l would equal an ethanol level of .021%. This is a very low blood alcohol level where the average individual appears normal.
Ethanol = alcohol. < 1.0 sounds like a reference range or cut off level for detection. Is this in relation to a urine test?
could u please give more info?was this a breathalyzer result?do u mean .10?
