How it works
Choose what to convert, pick the direction, and type your value — the answer appears instantly, with the exact conversion factor shown. Useful when your lab report uses different units from the guide you are reading.
Conversion factors used
Every factor below is a fixed, exact constant. The converter above applies these automatically.
| Convert | Multiply by | Example | |
|---|---|---|---|
| Glucose: mg/dL → mmol/L | ÷ 18.02 | 100 mg/dL = 5.55 mmol/L | Guide |
| Cholesterol: mg/dL → mmol/L | ÷ 38.67 | 200 mg/dL = 5.17 mmol/L | Guide |
| Triglycerides: mg/dL → mmol/L | ÷ 88.57 | 150 mg/dL = 1.69 mmol/L | Guide |
| Urea: mg/dL → mmol/L | × 0.1665 | 30 mg/dL = 5.00 mmol/L | Guide |
| Creatinine: mg/dL → µmol/L | × 88.4 | 1.0 mg/dL = 88.4 µmol/L | Guide |
| Vitamin D: ng/mL → nmol/L | × 2.5 | 30 ng/mL = 75 nmol/L | Guide |
| Calcium: mg/dL → mmol/L | × 0.2495 | 9.5 mg/dL = 2.37 mmol/L | Guide |
| Weight: lb → kg | × 0.4536 | 150 lb = 68.0 kg | |
| Height: in → cm | × 2.54 | 70 in = 177.8 cm | |
| Temperature: °F → °C | (°F − 32) × 5/9 | 98.6°F = 37.0°C |
Why units differ between labs
There are two measurement traditions in medicine. The United States mostly reports glucose and cholesterol in mg/dL (milligrams per decilitre — a mass concentration), while most of the world uses mmol/L (millimoles per litre — a molar concentration). Neither is more correct; they describe the same amount of substance in your blood.
India sits in the middle: glucose and lipid panels are usually reported in mg/dL, while electrolytes like sodium and potassium come in mmol/L. The practical rule is simple — always read your value against the reference range printed on the same report, in the same units. Convert only when you are comparing with a guide, an old report, or a doctor who uses the other system.
