Body Mass Index


Calculate Body Mass Index

Starvation
Underweight
Normal
OverWeight
Obese

Formula:

BMI in SI units = Weight in kg / ( Height in meters )2
BMI in US units = 703 X Weight in lbs / ( Height in inches )2
BMI in UK units = 6.35 X Weight in kg / ( Height in meter )2

BMI Example

Consider your weight to be 80 kgs and height 152 cms.

SI Units

Weight in kg / ( Height in meters )2
       = 80 / (1.52) 2
Your body mass index in SI units is 34.63.

US Units

703 X Weight in lbs / ( Height in inches )2
       = 703 * 176 / (59.84) 2
Your body mass index in US units is 35.21.

UK Units

6.35 X Weight in kg / ( Height in meter )2
       = 6.35 * 80 / (1.52) 2
Your body mass index in UK units is 219.9.

Note:

1 m = 0.01 cm
1 kg = 2.20462 lbs
1 inch = 2.54 cm
CategoryBMI range
