Serum Uric Acid Unit Converter (mg/dL ↔ µmol/L)

Convert a lab reading between milligrams per deciliter (used in the US, Pakistan, and India) and micromoles per liter (used in the UK, Canada, Europe, and Australia). Formula: 1 mg/dL = 59.48 µmol/L, from uric acid's molar mass of 168.11 g/mol.

5.8 mg/dL = 345 µmol/L

Below the 6.8 mg/dL (404 µmol/L) saturation point at 37°C, and below the 2020 ACR Guideline treat-to-target of 6 mg/dL (357 µmol/L) for gout patients receiving urate-lowering therapy.

Two reference points, and what they are: 6.8 mg/dL (404 µmol/L) is the physical saturation point of monosodium urate at normal body temperature (37°C, pH 7.4) — above it, crystals can form. Below 6 mg/dL (357 µmol/L) is the 2020 American College of Rheumatology Guideline's treat-to-target for people with gout who are receiving urate-lowering therapy. That target applies to gout patients on such therapy; it is not a universal target and not a personal recommendation. A single reading above or below either point does not diagnose anything — discuss your own target with your clinician.
