Frequently Asked Questions
Is BMI Calculator free?
Yes, completely free with no sign-up required. Calculate your BMI as many times as you need—whether daily or monthly—at no cost.
How accurate is the BMI calculation?
BMI calculations are mathematically precise using the standard formula: weight (kg) / height (m)². However, BMI is a screening tool, not a diagnostic tool. Muscle mass, bone density, and body composition aren't captured in BMI alone, so discuss results with your doctor for complete health assessment.
What does the healthy weight range mean?
The healthy weight range represents all weights where your BMI falls between 18.5 and 24.9, the "normal weight" category. Your specific range depends on your exact height and is shown when you calculate your BMI.
Should I use metric or imperial measurements?
Use whichever system is familiar to you. If you know your height and weight in pounds and inches, use imperial. If you measure in kilograms and centimeters, use metric. The calculator produces identical BMI results regardless of unit selection.
