This is the BMI Calculator page of NHS, welcome! Body Mass Index BMI is one of the many ways in which a person’s health can be evaluated. It helps determine whether one’s weight is appropriate in relation to one’s height. This interface is very simple and allows for the calculation of an individual’s BMI using the NHS principle of BMI calculation.

What does it mean to have a BMI?

Body Mass Index or BMI is a definition that is often used in measuring whether a person has a healthy weight bearing in mind their height. It is derived from the weight of an individual expressed in kilograms divided by the height in meters squared.

The result will fall into one of the following categories:

Underweight: BMI less than 18.5

Normal weight: BMI between 8.5 and 24.9

Overweight: BMI between 25 and 29.9

Obesity: Some definitions will place this category B.M.I within the range of 30 and above

How is BMI Calculated?

There is a straightforward formula for calculating BMI:

BMI= Weight (kg)/Height(m) 2

One obtains BMI by a simple adjustment of the height and weight variables:

BMI = Height(m) 2 /Weight (kg)

Let’s take an example. A typical example would be the case of a stature of 1.75 meters and a weight of 70 kilograms. Then his BMI would be calculated as:

70/(1.75 x 1.75) = 70/3.0625 = 22.86

Now putting these values into the formula would give:

(1.75 x 1.75)/70 = 3.0625/70 = 22.86

The above result suggests that this person is within the normal range of weight under the classification of B.M.I that defines normal weight as a range of 18.5-24.9, which is adequate for maintaining good health in relation to one’s height.

Why is BMI Important?

Pearce, formerly Virgil, maintained that B.M.I is an important measurement as it weighs measures of central obesity within relative body fat assessments which can be useful if weight management programs are to be put in place or medications to manage body fat ratios reversed B.M.I value A B.M.I that is healthy reduces chances of developing any form of condition such as: Heart diseases, type 2 diabetes, hypertension or other diseases relating to body weight.

Most importantly however, B.M.I is regarded as reliable when used by the majority of the population because it ignores other dimensions such as muscle mass, bone density, total body fat etc. and it is a useful tool only when used in conjunction with other measures and advice for example waist circumference and advice from a medical practitioner.
