Blood Test Unit Converter (mmol/L, mg/dL, nmol/L, ng/dL)
Australian labs report in SI units; most online references and US labs use conventional units. The conversion factors differ for every marker, and getting one wrong changes the interpretation completely.
1 mmol/L = 38.67 mg/dL

How do I convert cholesterol from mg/dL to mmol/L?
Divide by 38.67. For triglycerides divide by 88.57. The two factors differ because the molecules have different molecular weights.
How do I convert testosterone from ng/dL to nmol/L?
Multiply by 0.0347. A total testosterone of 500 ng/dL is 17.3 nmol/L.
How do I convert glucose from mg/dL to mmol/L?
Divide by 18. A fasting glucose of 100 mg/dL is 5.6 mmol/L.
