The Body Mass Index (BMI) Calculator or bmi check can be used to calculate BMI value and corresponding weight status while taking age into consideration. Note that the calculator also computes the Ponderal Index in addition to BMI, both of which are discussed below in detail.
BMI is a measurement of a person's leanness or corpulence based on their height and weight, and is intended to quantify tissue mass. It is widely used as a general indicator of whether a person has a healthy body weight for their height. Specifically, the value obtained from the calculation of BMI is used to categorize whether a person is underweight, normal weight, overweight, or obese depending on what range the value falls between.
Body mass index calculator is a value derived from the mass (weight) and height of a person. The BMI is defined as the body mass divided by the square of the body height, and is expressed in units of kg/m2, resulting from mass in kilograms and height in CM.
Who shouldn't use a BMI calculator or BMI for women
BMI calculator kg is not used for muscle builders, long distance athletes, pregnant women, the elderly or young children. This is because BMI does not take into account whether the weight is carried as muscle or fat, just the number. Those with a higher muscle mass, such as athletes, may have a high BMI but not be at greater health risk. Those with a lower muscle mass, such as children who have not completed their growth or the elderly who may be losing some muscle mass may have a lower BMI. During pregnancy and lactation, a woman's body composition changes, so using BMI is not appropriate.
|Category||BMI range - kg/m2|
|Severe Thinness||< 16|
|Moderate Thinness||16 - 17|
|Mild Thinness||17 - 18.5|
|Normal||18.5 - 25|
|Overweight||25 - 30|
|Obese Class I||30 - 35|
|Obese Class II||35 - 40|
|Obese Class III||> 40|
How to calculate Body Mass Index
Body Mass Index is a simple calculation using a person’s height and weight.
The formula is BMI = kg/m2 where kg is a person’s weight in kilograms and m2 is their height in metres squared.
A BMI of 25.0 or more is overweight, while the healthy range is 18.5 to 24.9.
BMI applies to most adults 18-65 years.
Check your body stats to find your ideal weight, because overweight and obesity are risk factors for diseases such as hypertension, heart disease and diabetes. It can also be used to find your healthy weight if you want to lose weight or are on diet.
