Uric acid µmol/L → mg/dL
Convert uric acid from µmol/L to mg/dL
Converts units only; reference ranges depend on the laboratory, the assay and the patient.
What is the Uric acid µmol/L → mg/dL?
This converter turns serum uric acid from µmol/L, the SI unit in UK, Scandinavian, French and Dutch reports and in much of the gout literature, into mg/dL, the unit most labs in Germany, Austria, Turkey and the USA use. It divides by 59.48 (equivalent to multiplying by about 0.01681), the factor derived from uric acid's molar mass of 168.11 g/mol.
When to use it
- Translating a urate value or target from an SI-based guideline or trial into mg/dL
- Entering urate into classification criteria, scores or forms whose categories are stated in mg/dL
- Reading letters or results from SI-reporting countries
When not to use it
- Values in mmol/L — multiply by 1000 to get µmol/L first
- Interpreting the value: reference ranges differ by sex, age and laboratory, and targets by guideline
How it is calculated
Uric acid (mg/dL) = uric acid (µmol/L) ÷ 59.48
Clinical pearls and limitations
- Converts units only; reference ranges depend on the laboratory, the assay and the patient.
- A quick check: 60 µmol/L is about 1 mg/dL, so dividing the µmol/L value by 60 gives a close estimate.
- Some reports print urate in mmol/L with three decimals; multiply by 1000 before using this converter.
- Thresholds that look round in one unit are usually not round in the other — a guideline's own printed pair beats a re-conversion.
- Uricase therapy (pegloticase, rasburicase) can degrade uric acid in the sample tube at room temperature; ask the lab about sample handling.
Frequently asked questions
How do I convert uric acid from µmol/L to mg/dL?
Divide by 59.48. For example, 357 µmol/L ÷ 59.48 = 6.0 mg/dL.
What is 300 µmol/L uric acid in mg/dL?
300 ÷ 59.48 = 5.04, about 5.0 mg/dL.
Why does a German lab report uric acid in mg/dL?
Germany, Austria and Turkey kept conventional mass units for many analytes. Both units describe the same measurement; only the scale differs.
