Medical Lab Unit Converter (SI ↔ Conventional)
Convert common laboratory results between conventional units (mg/dL, g/dL) and SI units (mmol/L, µmol/L, g/L). Pick an analyte, enter a value, and switch direction instantly.
Reference conversions between conventional and SI units. Verify against your lab’s reference ranges. Computed locally.
Supported analytes
Glucose, creatinine, urea (BUN), total cholesterol, triglycerides, total bilirubin, calcium, uric acid, albumin and haemoglobin. Each conversion uses the standard factor between conventional (mass/volume) and SI (molar) units. Always interpret values against your own lab’s reference ranges.
Frequently asked questions
How do I convert glucose from mg/dL to mmol/L?+
Multiply mg/dL by 0.0555. For example, 100 mg/dL × 0.0555 ≈ 5.55 mmol/L. To go back, divide mmol/L by 0.0555.
How do I convert creatinine from mg/dL to µmol/L?+
Multiply mg/dL by 88.4. So 1.0 mg/dL = 88.4 µmol/L.
Why do conventional and SI units differ?+
Conventional units (mg/dL) express mass per volume; SI units (mmol/L) express amount of substance per volume, using the analyte’s molecular weight. Many countries report labs in SI, so converting helps compare results.
