Lab unit converter
The same result looks like a completely different number depending on the units: glucose in mg/dL versus mmol/L, HbA1c in percent versus mmol/mol. Convert cleanly using published conversion factors, so you can compare units without changing the clinical meaning of the result.
Type a value in either box to convert. The other side updates instantly.
CDC/NHANES factor: mg/dL x 0.05551 = mmol/L.
A conversion changes the units only, never the meaning. What a value means for you depends on your own laboratory's reference range and your doctor.
