For convenience in determining accuracy, the factors used in this converter for each substance are displayed during conversion.

This tool will convert units (amount of substance, concentration) of clinical data between conventional units and SI units.
Warning:

When converting concentration of substances, You must be careful to ensure the unit prefix (amount or volume) in the data you are converting matches the unit prefix on the converter.
For example Acetaminophen:
converting mg/100 ml to µmol/L the factor = 66.16
converting µg/mL to µmol/L the factor = 6.616

The decimal point moves when either unit prefix changes.

Prefix notation

The value of the prefix notation allows rapid mental calculations to be performed (after much practice!).

The following concentrations are all the same:

0.5 M,

0.5 mol/l,

0.5 mmol/ml,

0.5 µmol/µl,

0.5 pmol/pl

You see that by scaling both the units (amount and volume) in the concentration up or down by a factor of 1000, the value of the concentration remains the same. If you only scale one of the terms (amount or volume), then you can express the same concentration in yet more ways:

0.5 mol/l = 0.5 mmol/ml = 500 µmol/ml = 500,000 pmol/µl .
