## Overview

For someone 170 cm tall and 70 kg, BMI is 24.2 — within the WHO Normal category (18.5–24.9) but only 1.8 BMI units from the Overweight threshold.

## Method

BMI is calculated as weight in kilograms divided by the square of height in metres: BMI = weight(kg) ÷ height(m)². Height in centimetres is converted to metres by dividing by 100 before squaring. The result is rounded to one decimal place. The WHO adult classification bands are: below 18.5 = Underweight; 18.5 to below 25 = Healthy weight; 25 to below 30 = Overweight; 30 to below 35 = Obese class I; 35 to below 40 = Obese class II; 40 and above = Obese class III. These thresholds are derived from population studies linking BMI ranges to the risk of weight-related health conditions and are published by the World Health Organization.
