A healthy BMI for most adults is between 18.5 and 24.9. BMI below 18.5 is underweight, 25-29.9 overweight, and 30+ obese. Athletes with higher muscle mass may have higher BMI without excess fat.

How is BMI calculated in metric and imperial?

Metric: BMI = weight(kg) / height(m)². Imperial: BMI = 703 x weight(lb) / height(in)². Our calculator auto-converts and supports cm/ft-in and kg/lb.

What is ideal weight based on BMI?

Ideal weight is the weight range that keeps your BMI 18.5-24.9 for your height. Formula: 18.5xh² to 24.9xh². We also show how much to gain or lose to reach it.

What does BMR and daily calories mean?

BMR (Mifflin-St Jeor) is calories your body burns at rest. Daily calories (TDEE) is BMR x activity level. Use it to plan maintenance, fat loss (~-15%) or lean gain (~+10%).

Is BMI accurate for everyone?

BMI is a screening tool, not a direct body-fat measure. It doesn't distinguish muscle vs fat, and its thresholds can differ for children, elders, and athletes. Combine with waist, body fat %, and medical advice for full picture.
