About this tool

What does BMI Calculator do?

Calculate body mass index from height and weight. The workspace keeps the input and result together, making it easy to check the change before you use it elsewhere.

For example, you can calculate body mass index from height and weight when you want to verify a calculation independently.

What you can control

BMI Calculator gives you direct control over height (cm).

How to use BMI Calculator

  1. 1

    Enter the weight (kg) carefully and check that the unit or format is correct.

  2. 2

    Set height (cm) to match the result you need.

  3. 3

    Run BMI Calculator, check the answer against your inputs, and copy the result if you need it elsewhere.

Tips for a better result

  • Keep the entered figures nearby so you can recheck the BMI Calculator answer and its assumptions.
  • Change one setting at a time—especially height (cm)—so differences are easier to compare.
  • Recheck the inputs and assumptions before using the result for an important decision.
