Lab unit converter
The same lab value looks like a completely different number depending on the units. Convert cleanly between conventional and SI units using the exact factors laboratories use, so you can compare results across reports without guesswork.
Type a value in either box to convert. The other side updates instantly.
Molar mass of glucose 180.16 g/mol; 1 mmol/L = 18.0182 mg/dL.
A conversion only changes the units, never the meaning. What a value means for you depends on your own reference range and your doctor.
