About This Tool
BMI Calculator estimates Body Mass Index from metric or imperial height and weight. Metric BMI = kg/(metres²). Imperial BMI = pounds/(inches²) × 703.
What You Can Do
Transparent method
Metric BMI = kg/(metres²). Imperial BMI = pounds/(inches²) × 703.
Input-driven result
BMI Calculator uses metric kg/cm or imperial lb/in.
Result interpretation
BMI rounded to one decimal and category
How to Use
- 1
Choose metric kilograms and centimetres or imperial pounds and inches
Choose metric kilograms and centimetres or imperial pounds and inches.
- 2
Enter the measured height and weight in the units shown by the active mode
Enter the measured height and weight in the units shown by the active mode.
- 3
Calculate BMI and read both the one-decimal value and its screening category
Calculate BMI and read both the one-decimal value and its screening category.
- 4
Interpret the result as a general screening measure rather than a diagnosis or direct body-fat measurement
Interpret the result as a general screening measure rather than a diagnosis or direct body-fat measurement.
Practical Use Cases
BMI Calculator scenario comparison
Compare how changes to metric kg/cm or imperial lb/in affect the bmi rounded to one decimal and category.
Arithmetic check
Use BMI Calculator to reproduce the documented formula with values you can independently verify.
Privacy and File Processing
Bmi Calculator keeps its Metric kg/cm or imperial lb/in input in browser memory while the operation runs. The workflow creates BMI rounded to one decimal and category for local preview or download and does not send the entered values or selected file bytes to the GXA Toolbox application server.
Supported Inputs and Outputs
Input
- Metric kg/cm or imperial lb/in
Output
- BMI rounded to one decimal and category
Formula / Method

Enter the metric kg/cm or imperial lb/in used by BMI Calculator.
Understanding the Result
BMI Calculator displays bmi rounded to one decimal and category.
Assumptions
- BMI is a screening measure, not a diagnosis or direct body-fat measurement.
- Category interpretation may be unsuitable for some ages, pregnancies, or body compositions.
Quality and Fidelity
Metric BMI = kg/(metres²). Imperial BMI = pounds/(inches²) × 703.
Limitations and Important Notes
- BMI is a screening measure, not a diagnosis or direct body-fat measurement.
- Category interpretation may be unsuitable for some ages, pregnancies, or body compositions.
Worked Example
70 kg and 175 cm gives BMI 22.9, displayed in the Healthy Weight range.
Helpful Tips
- Check the BMI Calculator units and rate periods before calculating.
- Retain enough precision in the bmi rounded to one decimal and category when using it in another calculation.
