mmolltomgdl.com is a free set of calculators for converting laboratory results between SI units (mmol/L and µmol/L) and conventional units (mg/dL). It is written and maintained by the mmolltomgdl.com Editorial Team.
Why This Site Exists
Most of the world reports blood tests in mmol/L, while the United States and some other countries use mg/dL. Each test has its own conversion factor, based on the molar mass of the substance measured, so a single “multiply by 18” rule only works for glucose. Patients comparing reports from different countries, students and health professionals all run into this problem. Our goal is to give the correct factor for each test, show the working, and explain the result in plain language.

How We Work
- Every conversion factor is calculated from the molar mass of the substance and checked against published SI conversion tables.
- Reference ranges come from published clinical guidelines, and each page lists its sources.
- Calculators are tested with known values in both directions, and each page shows when its factors were last verified.
- We correct confirmed errors promptly. See our editorial policy for details.
