Malunga nale khadi
Body Mass Index (BMI) is a simple ratio of weight to height used as a general indicator of whether your weight is in a healthy range. The formula is your weight in kilograms divided by the square of your height in metres (kg/m²); in imperial units it is 703 × pounds ÷ inches². The result drops into one of four bands — underweight, healthy, overweight or obese. Switch between metric and imperial units as you prefer.
For example, someone 175 cm tall weighing 70 kg has a BMI of 70 ÷ 1.75² = 70 ÷ 3.06 = 22.9, which sits in the healthy range of 18.5 to 24.9. For that height, a healthy weight runs from about 57 kg to 76 kg. The calculator also shows BMI Prime — your BMI divided by 25 — so a value under 1.0 means you are within the healthy limit.
Use BMI as a quick, free screen to see roughly where your weight sits and to track changes over time. It is a population-level tool, not a diagnosis: it cannot tell muscle from fat, so pair it with body fat percentage or a waist measurement for a fuller picture.
