Work out bmi for adults instantly with clear inputs, formula shown and shareable results.
BMI is weight in kilograms divided by height in metres squared. At 70 kg and 1.75 m it is 22.86, comfortably inside the 18.5-24.9 healthy band, which for that height spans 56.7 to 76.3 kg. BMI says nothing about how much of the weight is muscle, so heavily muscled people are routinely misclassified as overweight.
