Lab Unit Converter Formula

Worked Example

A creatinine result of 1.2 mg/dL:

1. Basis: M = 113.12 g/mol, so 1 mg/dL = 88.4 µmol/L
2. 1.2 mg/dL × 88.4 = 106.08 µmol/L

Factor (µmol/L → mg/dL): 0.011312217

Mass and molar units

US labs mostly report mass per volume (mg/dL); most other countries use amount per volume (mmol/L, µmol/L). The quantity measured is the same, so the conversion is exact once the molar mass is fixed.

• HbA1c Converter

  IFCC = (NGSP − 2.15) × 10.929, eAG = 28.7 × A1c − 46.7

  NGSP in %, IFCC in mmol/mol, eAG estimated average glucose in mg/dL (ADAG study)

  Example: An HbA1c of 7 %: HbA1c (IFCC) = 53.0056 mmol/mol.

• Cholesterol Converter

  mmol/L = mg/dL ÷ 38.67 (cholesterol), ÷ 88.57 (triglycerides)

  factors from the molar mass of cholesterol (386.65 g/mol) and of triolein (885.7 g/mol)

  Example: A total cholesterol of 200 mg/dL: Cholesterol = 5.17197 mmol/L.
