Health unit converters On-device
Convert weight, height, temperature and blood-test units
Weight
Height
Body temperature
Reference: 37°C equals 98.6°F, a commonly cited normal baseline. This is a unit conversion only — it does not assess fever.
Blood test units
Unit conversions for reference only — not medical advice. Ask a clinician or your lab to interpret any result.
Free health unit converters: kilograms to pounds, centimetres to feet and inches, Celsius to Fahrenheit, and blood-test units (mg/dL to mmol/L) for cholesterol, triglycerides and glucose. Works entirely on your device.
About this tool
What you provide
- A weight in kg or lb, a height in cm or ft/in, or a body temperature in °C or °F
- A blood-test value in mg/dL or mmol/L, with the test chosen: cholesterol, triglycerides or glucose
What you get
- The same value in the other unit
- For blood tests, the conversion made with that test's own factor
Limits
- Blood-test conversions branch by test — cholesterol, triglycerides and glucose do not share a factor, so the wrong test gives the wrong number.
- The temperature row converts the unit only; it does not assess fever.
- Unit conversions for reference only — not medical advice. Ask a clinician or your lab to interpret any result.
How to use it
-
Find the row you need
The page holds four independent rows — Weight, Height, Body temperature and Blood test units — and each works on its own.
-
Pick the blood test first
For the blood-test row, choose Cholesterol, Triglycerides or Glucose, because each one converts with its own factor.
-
Type into either side
Enter a value in either box of a row and the opposite box fills in as you type — the height row fills feet and inches together, and the temperature row converts units only and makes no judgement about fever.
