Creatinine µmol/L → mg/dL
Convert serum creatinine from SI (µmol/L) to conventional units (mg/dL)
Converts units only. Creatinine-based eGFR equations such as CKD-EPI take mg/dL.
What is the Creatinine µmol/L → mg/dL?
Serum creatinine is reported in µmol/L in most of Europe and in mg/dL in Germany, Austria, Turkey and the USA. The conversion factor of 88.4 µmol/L per mg/dL comes from creatinine’s molar mass (113.12 g/mol) and is the factor in the AMA Manual of Style SI table.
When to use it
- Entering a European creatinine into an equation defined in mg/dL (CKD-EPI, Cockcroft–Gault)
- Comparing results from labs that report different units
- Reading international guidelines or papers
When not to use it
- Urine creatinine in mmol/L — convert to µmol/L first (× 1000)
- As a measure of kidney function on its own; use an eGFR equation
How it is calculated
Creatinine (mg/dL) = creatinine (µmol/L) ÷ 88.4
Clinical pearls and limitations
- Converts units only. Creatinine-based eGFR equations such as CKD-EPI take mg/dL.
- 1 mg/dL = 88.4 µmol/L; 100 µmol/L ≈ 1.13 mg/dL.
- Enzymatic and Jaffe methods differ slightly; IDMS-traceable assays are standard in Europe.
- Creatinine depends on muscle mass, so the same value means different GFRs in different people.
Frequently asked questions
How do I convert creatinine from µmol/L to mg/dL?
Divide by 88.4. For example, 120 µmol/L ÷ 88.4 = 1.36 mg/dL.
What is 1 mg/dL creatinine in µmol/L?
88.4 µmol/L.
Why do German labs report creatinine in mg/dL?
Germany and Austria kept conventional mass units for several analytes; both units describe the same measurement.
