Lab units converter: mg/dL, mmol/L, µmol/L, mEq/L

Units & conversions

Converts the common chemistry results between conventional US units and SI units, and shows mEq/L where the ion carries a charge. Each factor comes from the molar mass, so it is exact arithmetic, not an estimate.

What you enter

Analyte: Glucose / Creatinine / Urea (from BUN) / Calcium / Magnesium / Phosphate (as phosphorus) / Uric acid / Bilirubin / Cholesterol (total, LDL, HDL) / Triglycerides / Sodium, potassium, chloride, bicarbonate / Haemoglobin / Albumin or total protein
Your value is in: Conventional (mg/dL) / SI (mmol/L)
Value

FORMULASI value = conventional value x factor. Factor = 10 / molar mass for mg/dL to mmol/L, 10000 / molar mass for mg/dL to µmol/L, 10 for g/dL to g/L. mEq/L = mmol/L x charge (2 for calcium and magnesium).
