The calculator uses the standard BMI formula:
Where:
Explanation: BMI is calculated by dividing weight in kilograms by the square of height in meters.

Tips: Enter weight in kilograms and height in meters. For accurate results, measure weight without heavy clothing and height without shoes.
Q1: What is a healthy BMI range for women?
A: For adult women, a BMI between 18.5 and 24.9 is considered healthy. Below 18.5 is underweight, 25-29.9 is overweight, and 30+ is obese.
Q2: Does BMI differ for men and women?
A: The BMI calculation is the same, but healthy ranges may vary slightly due to differences in body composition.
Q3: What are the limitations of BMI?
A: BMI doesn't account for muscle mass, bone density, overall body composition, or racial and sex differences.
Q4: Is BMI accurate for athletes?
A: BMI may overestimate body fat in athletes with high muscle mass and underestimate it in older people with less muscle mass.
Q5: Should pregnant women use BMI?
A: BMI calculations during pregnancy aren't accurate due to weight gain from the baby. Consult your doctor for appropriate weight guidelines.
