To convert glucose, total / LDL / HDL cholesterol or triglycerides between mmol/L and mg/dL, use the Lab Unit Converter.
Unit conversion only. Normal ranges differ for armpit, oral, ear and rectal readings; ask a clinician whether a temperature is a fever or a weight is healthy.
Estimates based on general formulas, for information only. Not a substitute for professional medical advice, diagnosis or treatment.
Unit conversion only. It does not tell you whether you have a fever or a healthy weight. Body temperature depends on where it is measured; ask a clinician if you feel unwell.
How it works
When to use it
- Reading height and weight on medical, passport or visa forms that use the other unit system.
- Converting a Fahrenheit thermometer reading or health advice written in Celsius.
Formula
inches = cm ÷ 2.54; feet = whole part of inches ÷ 12, the remainder is inches1 in = 2.54 cm exactly.
lb = kg ÷ 0.453592371 lb = 0.45359237 kg exactly.
°F = °C × 9/5 + 32; °C = (°F − 32) × 5/9Worked example
Given: Height 175 cm, weight 70 kg, temperature 38.5 °C
- Height: 175 ÷ 2.54 ≈ 68.9 in; 68.9 ÷ 12 = 5 remainder 8.9, so 5 ft 8.9 in.
- Weight: 70 ÷ 0.45359237 ≈ 154.3 lb.
- Temperature: 38.5 × 9/5 + 32 = 101.3 °F.
Result: 5′8.9″, 154.3 lb, 101.3 °F.
Reading the result
- Imperial heights are usually rounded to the nearest inch, so 5 ft 8.9 in is written 5′9″.
- Converting changes only the unit. Armpit readings run lower than oral or ear readings, so compare against the range for the same site.
Limitations
- Uses the avoirdupois pound, not the troy pound.
- It does not judge whether a weight is healthy; see BMI and ask a clinician.

How do I convert body temperature?
°F = °C × 9/5 + 32 and °C = (°F − 32) × 5/9. For example 38.5 °C = 101.3 °F and 100.4 °F = 38 °C.
