Convert clinical lab values between conventional and SI units (glucose, cholesterol, creatinine, haemoglobin and more).
A medical unit converter handles the unit conversions that come up daily in clinical work — blood glucose (mmol/L ↔ mg/dL), creatinine (μmol/L ↔ mg/dL), cholesterol (mmol/L ↔ mg/dL), weight (kg ↔ lb), height (cm ↔ inches), and temperature (°C ↔ °F).
The US uses conventional units (mg/dL, lb, °F) while most of the world uses SI units (mmol/L, kg, °C). Patient records from international referrals, online medical literature, and many drug references mix the two — accurate conversion prevents prescription errors and clinical misinterpretation.
Inputs: Common medical unit conversions
Conventional units (mg/dL) developed historically in 19th-century US laboratories and persist today by inertia. SI units (mmol/L) were standardised internationally in 1960 and are favoured in modern medicine because they directly express molarity — chemically meaningful for understanding receptor binding, drug kinetics, and metabolic pathways. The USA is the last major holdout against full SI adoption in clinical medicine.
Use the unit system standard for your local practice and the patient's usual care. If presenting to international colleagues or publishing research, default to SI units. If converting between systems for any clinical decision (especially drug doses), write BOTH the converted value AND the unit clearly — never leave a number without units in a clinical record.
