How to use BMI Calculator

    Frequently asked questions

    Does this support imperial units?

    Yes. You can switch between metric and imperial input modes.

    Is this medical advice?

    No. BMI is a screening metric and does not replace medical guidance.

    How does the BMI calculator determine the 'healthy weight range' it displays?

    It back-calculates the weight range that produces a BMI between 18.5 and 24.9 for your entered height, using the standard WHO classification thresholds.

    Is the BMI formula different for metric versus imperial inputs?

    The underlying formula is the same (weight divided by height squared); the tool simply converts imperial values to metric before computing so results are consistent.

    Does this tool account for factors like age, sex, or muscle mass in its assessment?

    No, BMI is a simple weight-to-height ratio and does not factor in body composition; athletes or older adults should consult a healthcare provider for a fuller assessment.
