Creatinine Unit Converter

In short Creatinine is reported in mg/dL in some countries and µmol/L in others, and the two are related by a fixed factor: 1 mg/dL = 88.4033 µmol/L, so to go the other way you divide by 0.0113118. 0.8 mg/dL is 71 µmol/L; 1.0 mg/dL is 88 µmol/L; 1.5 mg/dL is 133 µmol/L. The factor is not arbitrary — it comes from the molar mass, because creatinine has a molar mass of 113.12 g/mol, and that is why every analyte has its own factor rather than one shared conversion. Creatinine is the one where the two systems look most alarmingly different — 1.0 mg/dL and 88 µmol/L are the same result, but one is a small decimal and the other is a three-figure number, and people reading their own results across systems routinely think something has gone badly wrong. Note the SI unit here is µmol/L, a thousand times smaller than the mmol/L used for glucose. This converts units. It does not interpret results, does not compare your value against a reference interval, and is not a substitute for the clinician who ordered the test — reference intervals differ between laboratories, methods and populations.
