Step-by-step solution
- Basis: conventional factor 38.67 (cholesterol, M ≈ 386.65 g/mol)
- 200 mg/dL × 0.02585984 = 5.171967934 mmol/L
Cholesterol Converter Formula
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)
Worked Example
A total cholesterol of 200 mg/dL:
- Basis: conventional factor 38.67 (cholesterol, M ≈ 386.65 g/mol)
- 200 mg/dL × 0.02585984 = 5.171967934 mmol/L
Factor (mmol/L → mg/dL): 38.67

SI value = conventional value × factor
factor = 10 ÷ M for mg/dL → mmol/L, 10,000 ÷ M for mg/dL → µmol/L, 1000 ÷ M for ng/mL → nmol/L (M in g/mol)
Example: A creatinine result of 1.2 mg/dL: Creatinine = 106.08 µmol/L.
Frequently asked questions
Why are cholesterol and triglyceride factors different?
Each factor is based on a molar mass: cholesterol about 386.65 g/mol, triglycerides (as triolein) about 885.7 g/mol, so the same mg/dL is fewer mmol/L of triglyceride.
Do LDL and HDL use the same factor?
Yes. LDL, HDL and non-HDL are reported as their cholesterol content, so all use 38.67.
