Calculator
Formula used
- BMI = m / h², where m is mass (kg) and h is height (m).
- Recommended mass from BMI bounds: m = BMI × h².
- Weight force: W = m × g, where g is gravitational acceleration (m/s²).
- Unit helper: 1 N ≈ 0.22481 lbf.
This tool treats “weight” as a force. On different worlds, mass stays the same, but weight force changes with g.
How to use this calculator
- Choose a height unit and enter your height.
- Select a gravity preset, or enter a custom g.
- Pick a BMI model: healthy range, custom range, or target BMI.
- Optional: enter a measured mass to compute your BMI and weight.
- Press Submit to show results above the form.
- Use Download CSV or Download PDF for saving outputs.
