BMI calculator

A BMI calculator is a tool that calculates a person’s body mass index (BMI) based on their height and weight. BMI is a measurement of body fat based on an individual’s height and weight, and it is commonly used as a screening tool to identify potential health problems related to weight.

Here’s a table of BMI ranges:

BMI Category BMI Range
Underweight < 18.5
Normal weight 18.5 - 24.9
Overweight 25.0 - 29.9
Obesity class I 30.0 - 34.9
Obesity class II 35.0 - 39.9
Obesity class III ≥ 40.0

The formula for calculating BMI is weight (kg) divided by height (m) squared. Here’s the formula in more detail:

BMI = weight (kg) / height (m)²

To calculate BMI using pounds and inches, the formula is slightly different:

BMI = (weight (lbs) / height (in)²) x 703
