### Calculate Body Mass Index

Body Mass Index is a simple calculation using a person’s height and weight.

The BMI formula is: BMI = Kg / (m)2. Here are the standard BMI ranges

- 1 inch = 2.54 centimeters
- 1 meter = 100 cm
- 1 pound = kilogram

### BMI formula

The body mass index formula is easy to determine. It’s a simple calculation that takes into account your weight and height.

- The imperial BMI formula = Weight (LBS) x 703 ÷ Height (Inches²)
- The metric BMI formula = Weight (KG) ÷ Height (Metres²)

This calculator computes the body mass index and rates it appropriately for men and women.

### Children’s BMI:

For children and young people aged 2 to 18, the BMI calculator takes into account age and gender as well as height and weight.

### Ideal Body Weight Calculator

There are several ways you can determine your ideal weight. The most common methods are:

- Body Mass Index (Weight and Height)
- Waist-to-Hip Ratio (WHR)
- Body Fat Percentage

BMI < 18.5: Below normal weight

BMI >= 18.5 and < 25: Normal weight

BMI >= 25 and < 30: Overweight

BMI >= 35 and < 40: Class II Obesity

BMI >= 40: Class III Obesity

### Waist-to-Hip Ratio (WHR)

This measurement checks how much fat is stored around your hips, waist, and buttocks. It basically compares your hip circumference with your actual waist size.

**WHR = WC/HC**
