A body fat calculator, known as the Durnin and Womersley formula, is a mathematical equation that estimates an individual’s body fat percentage. It involves measuring specific skinfold thicknesses at different body sites, such as the chest, abdomen, and thigh.
Developed in 1974 by John Durnin and John Womersley, this calculator is widely used in fitness and medical settings due to its accuracy and ease of use. Its simplicity and the use of inexpensive equipment make it accessible for both professionals and individuals tracking their body composition.
