Uric acid mg/dL → µmol/L
Convert uric acid from mg/dL to µmol/L
Converts units only; reference ranges depend on the laboratory, the assay and the patient.
What is the Uric acid mg/dL → µmol/L?
Serum uric acid (urate) is reported in mg/dL by most labs in Germany, Austria, Turkey and the USA, and in µmol/L in the UK, Scandinavia, France, the Netherlands and many other countries. This converter multiplies by 59.48, which follows from the molar mass of uric acid (168.11 g/mol): 1 mg/dL = 10 mg/L, and 10 000 ÷ 168.11 ≈ 59.48 µmol/L.
When to use it
- Comparing a mg/dL urate value with gout or CKD literature written in µmol/L
- Following urate-lowering therapy when results come from labs using different units
- Preparing case reports or exam answers in SI units
When not to use it
- Urinary uric acid excretion reported per 24 h — check the unit (mg/24 h vs mmol/24 h) and convert accordingly
- Deciding on treatment targets: these depend on the guideline and the clinical situation
How it is calculated
Uric acid (µmol/L) = uric acid (mg/dL) × 59.48
Clinical pearls and limitations
- Converts units only; reference ranges depend on the laboratory, the assay and the patient.
- Some tables round the factor to 59.5; the difference is clinically negligible.
- 'Uric acid' and 'urate' refer to the same measurement in serum; at physiological pH it circulates mainly as urate.
- Serum urate can be normal or low during an acute gout flare, so a single value does not exclude gout.
- SI results are usually printed as whole µmol/L; do not over-interpret decimals after converting.
Frequently asked questions
How do I convert uric acid from mg/dL to µmol/L?
Multiply by 59.48. For example, 6 mg/dL × 59.48 = 356.9, about 357 µmol/L.
What is 8 mg/dL uric acid in µmol/L?
8 × 59.48 = 475.8, about 476 µmol/L.
Where does the factor 59.48 come from?
From the molar mass of uric acid, 168.11 g/mol. Dividing 10 mg/L by 168.11 mg/mmol gives 0.05948 mmol/L, i.e. 59.48 µmol/L per mg/dL.
