The body mass index is used as a guide to establish whether an individual’s weight is within a healthy range or if they are at risk from certain medical conditions due to being over or under weight.

As no two bodies are the same, the index takes into account an individuals’ height and weight and calculates a number specific to them. This number will then give the individual guide as to whether their weight is within a healthy range.

Calculating Body Mass Index

To calculate his body mass index, an individual should divide his weight (in kilograms) by the square of his height (in metres).
