What is the BMI formula?

BMI which comes from Body Mass Index is a popular body shape indicator that many people use when speaking about their ideal weight. This body health indicator is not a measure of body fat but offers a rough image of how far or close somebody is to the ideal body weight

Body Mass Index in English units = mass (lbs) / [height (in)^2] * 703.06957964

Body Mass Index in Metric units = mass (kg) / [height (m)^2]

How about ideal weight?

Ideal body weight is considered to be a healthy level of the body’s weight. There is no 100% accurate equation than can estimate ideal body weight, the formulas released so far provide an approximate value. The form above uses the five ideal weight formulas which were released by scientists such as J.D. Robinson and D.R. Miller in 1983, B.J. Devine in 1974, G.J. Hamwi in 1964.
