A study tool, not a clinical one

This page exists for converting uric acid between mg/dL and µmol/L, and learning where the factor between the two units comes from. It is not clinical decision support and must not be used to treat anybody.

Read a result against its own report. Laboratories differ in method and in the population they set reference intervals from, so interpret a converted number against the ranges printed on the report it came from.
The factor belongs to uric acid. Applied to any other analyte, it gives a number that looks just as plausible and is wrong.
Every calculation here is shown, not hidden. If a step does not match what you were taught, follow the working rather than the output, and tell us if we have it wrong. How the pages are checked is set out in the editorial policy.

Why the factor is specific to uric acid

Uric acid, C₅H₄N₄O₃, has a molar mass of 168.112 g/mol, summed from the standard atomic weights of its atoms. A result in mg/dL is a mass and one in µmol/L an amount of substance, so converting divides by the molar mass and multiplies by 10,000: 10 for the decilitres in a litre, times 1000 for the micromoles in a millimole: 1 mg/dL = 10,000 ÷ 168.112 = 59.4842 µmol/L.

A factor fits one analyte only: 1 mg/dL of creatinine is 88.4017 µmol/L, as the creatinine conversion table shows.

µmol/L = mg/dL × 10,000 ÷ 168.112
mg/dL = µmol/L × 168.112 ÷ 10,000
mmol/L = mg/dL × 10 ÷ 168.112
mg/dL = mmol/L × 168.112 ÷ 10

Which countries report which unit

American and Indian laboratories usually report uric acid in mg/dL. British and Canadian ones report µmol/L, and Australian ones mostly mmol/L, so 0.36 mmol/L and 360 µmol/L are the same result from two reports.

Worked example

6 mg/dL in µmol/L
= 6 × 10,000 ÷ 168.112
= 356.905 µmol/L
