How to Use the Creatinine mg/dL to µmol/L Calculator
Choose the conversion direction, enter the creatinine value from your lab report, and read the result instantly. The calculator supports both mg/dL to µmol/L and µmol/L to mg/dL conversions.
Use the quick convert buttons for common serum creatinine examples, or type any decimal value. The formula strip shows the exact calculation so you can verify the result.
This page is focused only on creatinine, so you do not need to choose a molecule or worry about using a glucose or cholesterol factor by mistake.
Creatinine Conversion Formula
Creatinine is commonly reported in mg/dL in the United States and in µmol/L in many international lab reports. The standard conversion factor is 88.4.
Creatinine µmol/L = Creatinine mg/dL × 88.4 Creatinine mg/dL = Creatinine µmol/L ÷ 88.4 Example Conversion
If your creatinine result is 1.0 mg/dL, multiply by 88.4:
1.0 × 88.4 = 88.4 µmol/L A creatinine value of 88.4 µmol/L is therefore equal to 1.0 mg/dL.
For the reverse direction, divide by 88.4. For example, 100 µmol/L divided by 88.4 equals about 1.13 mg/dL.

Why Creatinine Units Matter
Creatinine is a waste product from normal muscle metabolism. Blood creatinine is used with age, sex, and other details to estimate kidney filtration, often reported as eGFR.
Unit confusion can make the same result look very different. For example, 1.2 mg/dL and 106 µmol/L describe roughly the same creatinine concentration. Converting the units helps you compare lab reports from different countries or healthcare systems.
Creatinine vs eGFR
Creatinine is the lab value being converted on this page. eGFR is a separate kidney filtration estimate calculated from creatinine plus personal factors such as age and sex. A unit conversion can help you read the creatinine number, but it does not replace an eGFR calculation or a clinician's interpretation.
If two reports show different units, convert the creatinine value first, then compare the eGFR, reference range, and trend over time.
Creatinine Reference Range Notes
Typical creatinine reference ranges vary by lab, age, sex, body size, muscle mass, pregnancy status, and kidney function. A value that is normal for one person may be concerning for another.
Creatinine should not be interpreted alone. Healthcare providers often review it together with eGFR, blood urea nitrogen (BUN), urine albumin, medications, hydration status, and the trend over time.
Common Mistakes to Avoid
Do not use the general mg/dL to mmol/L factor for creatinine unless the calculator is specifically set to creatinine. Each substance has a different molecular weight, so glucose, calcium, bilirubin, and creatinine do not share one universal factor.
Also check whether the report says µmol/L or mmol/L. Creatinine is usually shown in µmol/L internationally. If a value is written in mmol/L, it is 1,000 times larger than µmol/L and should be handled carefully.
Finally, avoid judging kidney function from one converted number alone. A rising creatinine trend can matter even when one result is only mildly outside the reference range.
Frequently Asked Questions
How do you convert creatinine mg/dL to µmol/L?
Multiply the mg/dL value by 88.4. For example, 1.0 mg/dL equals 88.4 µmol/L.
How do you convert creatinine µmol/L to mg/dL?
Divide the µmol/L value by 88.4. For example, 88.4 µmol/L equals 1.0 mg/dL.
Is 100 µmol/L creatinine the same as 1 mg/dL?
No. 100 µmol/L is about 1.13 mg/dL. A value of 1.0 mg/dL is equal to 88.4 µmol/L.
What is 1.2 mg/dL creatinine in µmol/L?
1.2 mg/dL multiplied by 88.4 equals about 106.1 µmol/L.
What is 90 µmol/L creatinine in mg/dL?
90 µmol/L divided by 88.4 equals about 1.02 mg/dL.
Can this calculator diagnose kidney disease?
No. This tool only converts units. Kidney disease assessment requires clinical interpretation, eGFR, urine testing, and medical context.
Does this calculator work for urine creatinine?
The unit math is the same, but urine creatinine is often reported with different specimen types and clinical meaning. Always compare urine results with the reference range on that specific report.
Conclusion
This creatinine mg/dL to µmol/L calculator gives you a fast way to compare kidney lab results across different unit systems. Use it for unit conversion, then ask your healthcare provider to interpret what the result means for your health.
