How do I convert glucose from mg/dL to mmol/L?

Divide the mg/dL value by 18 (or multiply by 0.0555). For example, 90 mg/dL ÷ 18 = 5.0 mmol/L. The converter does this automatically in both directions.

How do I convert creatinine from mg/dL to µmol/L?

Multiply the mg/dL value by 88.4. For example, 1.0 mg/dL × 88.4 = 88.4 µmol/L.

Are these conversions exact?

They use standard molar-mass factors and are accurate for clinical use, but always confirm critical values against your local laboratory's units and reference ranges.

Medical Unit Converter

Convert lab values between SI (mmol/L, µmol/L, g/L) and conventional (mg/dL, g/dL) units.

Instantly convert common laboratory measurements — glucose, cholesterol, creatinine, urea, bilirubin, haemoglobin and albumin — between international (SI) and conventional (US) units. Type in either box and the other updates automatically.

Conversions use standard factors. Both fields update as you type. Always check critical values against your local laboratory's units and reference ranges.

Conversion factors

Measurement	SI unit	Conventional	Relationship
Glucose	mmol/L	mg/dL	1 mmol/L = 18.0 mg/dL
Total cholesterol	mmol/L	mg/dL	1 mmol/L = 38.67 mg/dL
LDL / HDL cholesterol	mmol/L	mg/dL	1 mmol/L = 38.67 mg/dL
Creatinine	µmol/L	mg/dL	1 mg/dL = 88.4 µmol/L
Urea / BUN	mmol/L (urea)	mg/dL (BUN)	urea = BUN × 0.357; BUN = urea × 2.8
Bilirubin	µmol/L	mg/dL	1 mg/dL = 17.1 µmol/L
Haemoglobin	g/L	g/dL	g/L = g/dL × 10
Albumin	g/L	g/dL	g/L = g/dL × 10
