Calculator
Formula Used
Creatinine conversion is based on the molecular relationship between the two reporting units. The standard conversion factor is 88.4.
- µmol/L = mg/dL × 88.4
- mg/dL = µmol/L ÷ 88.4
Example: a creatinine value of 1.20 mg/dL becomes 106.08 µmol/L. A value of 100 µmol/L becomes 1.13 mg/dL when rounded to two decimals.

FAQs
1) What is creatinine?
Creatinine is a waste product formed from normal muscle metabolism. Laboratories measure it in blood or urine because it helps assess kidney filtration and related clinical trends.
2) Why do I need to convert creatinine units?
Different laboratories and countries report creatinine in different units. Converting values helps you compare reports, follow treatment records, and understand research or international lab references.
3) What is the conversion factor between mg/dL and µmol/L?
The accepted factor is 88.4. Multiply mg/dL by 88.4 to get µmol/L, or divide µmol/L by 88.4 to return to mg/dL.
4) Can rounding change the displayed result?
Yes. The exact converted number may contain several decimals. Rounding changes only the displayed precision, not the underlying conversion factor used in the calculation.
5) Does this calculator diagnose kidney disease?
No. It converts units only. Diagnosis requires a clinician, your symptoms, laboratory reference intervals, estimated GFR, medical history, and sometimes repeat testing.
6) Can I enter multiple values for trend review?
Yes. Paste several values separated by commas, semicolons, or new lines. The calculator will convert them, build a table, and display a Plotly chart.
7) Which unit is more common?
Both are common, depending on region and laboratory practice. Many U.S. reports use mg/dL, while many international laboratories report creatinine in µmol/L.
8) Should I use this result for medication dosing?
Use caution. Medication decisions usually depend on broader renal assessment, such as eGFR or creatinine clearance, not unit conversion alone.
