BMI calculator

Calculate adult BMI from weight and height. A general index, not a diagnosis: it does not distinguish muscle and fat or apply in the same way during pregnancy or childhood.

Basal metabolic rate

Estimate resting energy with Mifflin–St Jeor (ages 19–78). Not a clinical measurement of basal metabolism. Not for pregnancy, breastfeeding or medical conditions.

Calorie needs

Indicative energy estimate: Mifflin–St Jeor × chosen PAL (1.4–2.4), for healthy adults 19–78. Not a diet prescription; excludes pregnancy, breastfeeding and medical conditions.

Running pace

Calculate average pace per km and mile and speed from distance and time. Projections assume constant pace and do not predict performance or endurance.
