BMI (body mass index) also known as Quetelet index - is used to estimate a healthy body weight based on a person's height, assuming an average body composition. Body mass index is defined as the individual's body weight divided by the square of height.
The formula for Ideal Weight Calculator is:
BMI = m / h2
m - body mass [kg]
h - body height [m]
The BMI factor is generally used as approximation of body fat level.
High BMI (overweight and obese) causes increased risk for many diseases and/or health conditions. The BMI formula is simple: all inputs for the formula are just weight and height. It can be calculated quickly and without expansive equipment.
However BMI ignores many individual factors such as: frame size, muscularity, etc. Ideal Weight Calculator also ignores specific conditions of athlete, child, the elderly, the infirm, pregnant etc.
