Creatinine Unit Converter (mg/dL ↔ µmol/L)
Convert creatinine between mg/dL and µmol/L in either direction. Enter a value and the result updates instantly. This page performs unit conversion and cites where the factor and the reference intervals come from; it does not interpret your value.
The creatinine conversion factor and where it comes from
Creatinine is a waste product of muscle metabolism filtered by the kidneys, reported on a basic or comprehensive metabolic panel. Creatinine is reported in mg/dL on U.S. lab reports and in µmol/L on UK, Canadian, Australian, and most European reports.
The standard conversion factor for creatinine is 88.42, applied as mg/dL × 88.42 = µmol/L (and µmol/L ÷ 88.42 = mg/dL in reverse). Because creatinine's molecular weight (113.12 g/mol) is small and the SI unit is µmol/L (micromoles, not millimoles), the factor 88.42 is much larger than the mg/dL to mmol/L factors used for lipids.

Published reference intervals
The intervals below are reproduced from U.S. National Library of Medicine, MedlinePlus: Creatinine blood test. They are listed here for unit reference only. Whether any value is in range for you depends on your laboratory's own reference range and your clinical context, so read them alongside your report and your healthcare provider, not in place of either.
| Category | mg/dL | µmol/L |
|---|---|---|
| Typical reference: men | 0.74-1.35 mg/dL | 65.4-119.3 µmol/L |
| Typical reference: women | 0.59-1.04 mg/dL | 52.2-91.9 µmol/L |
Reference ranges vary by laboratory, assay, age, sex, and muscle mass; the values above are representative adult ranges published by the source.

Common questions
How do I convert creatinine from mg/dL to µmol/L?
Multiply by 88.42: mg/dL × 88.42 = µmol/L. To go the other way, divide by 88.42 (or multiply by 0.0113).
What is the creatinine conversion factor?
88.42. Because creatinine's molecular weight (113.12 g/mol) is small and the SI unit is µmol/L (micromoles, not millimoles), the factor 88.42 is much larger than the mg/dL to mmol/L factors used for lipids.
Where is mg/dL used and where is µmol/L used?
Creatinine is reported in mg/dL on U.S. lab reports and in µmol/L on UK, Canadian, Australian, and most European reports.
