You can then follow this figure to see your BMI value and weight category. To use this table, you just need to find your weight in the left-hand column and then follow it across to find your height. A BMI graph, table or chart are also excellent to use as a BMI checker if you’re trying to lose weight and want to monitor your progress. BMI ChartīMI charts are helpful as they give you a visual illustration of your BMI in relation to the general population and show you your weight category. Most calculators will also indicate the weight category your BMI measurement falls within. x 703 = 24.96 (BMI of 24.96) BMI calculatorĪn online body mass index calculator uses the same formula but provides a quicker and simpler way to determine BMI.Īll you need to do is simply enter your weight and height in either imperial or metric measurements into the BMI calculator, and it will calculate your BMI for you. If you’re 5’5” (65 inches) in height and 150lbs in weight, your BMI calculation would be: The imperial BMI formula is your weight in pounds (lbs) divided by your height in inches, squared, and then you multiply this figure by a conversion factor of 703.īMI = x 703 If you are 1.75m in height and 75kg in weight, your BMI calculation would be:ħ5kg / (1.75m²) = 24.49kg/m² (BMI of 24.49) The metric formula for BMI is weight in kilograms divided by height in meters squared. You use the same formula whether you’re working out BMI for men or BMI for women. There are two BMI calculation formulas to calculate BMI, depending on whether you’re using metric or imperial measurements. You can use a Body Mass Index calculator, work it out manually using the BMI formula, or look at a BMI graph or chart. You can use several methods to calculate your body mass index using metric or imperial figures. Today, the BMI scale remains a simple and expensive way to classify people according to their weight category so that they can be screened for various health conditions.īMI is calculated using your height and weight measurements to estimate your level of body fat and indicates if you are within a healthy weight range. Note that, in our BMI calculator, the 'Upper Weight Limit' depends on age and sex, so it is not fixed as in other calculators.Belgian statistician, Adolphe Quetelet, first developed the BMI (Body Mass Index) in the 1800s. Here is the BMI Prime formula: BMI' = Actual Weight/ Upper Weight Limit It is a simple modification of the familiar Body Mass Index (BMI) system.īMI Prime is defined as the ratio of a person’s Actual Weight (or Mass) to his Upper Weight (or Mass) Limit of the “healthy weight” range. What is BMI Prime?īMI Prime (abbreviated BMI’) is an index of total body fat content. If your height is 1.7 meter and you weigh 65 kilograms (kilos), your BMI isįinally, BMI = 22.5 kg/m 2 (rounded).
Here is the BMI formula in the metric system where weight is in kilograms, and height is in meter: BMI = weight/ (height) 2 Furthermore, our BMI calculator is better than the standard BMI calculator once it includes both sex and age into its algorithm. On the other hand, someone with a light bone structure might be considered of normal weight, even if they have excess body fat.Īlthough some factors like, bone structure and muscle mass are not part of the equation when IMC is calculated, Body Mass Index can be helpful to set limits such as underweight, normal or obese, for individuals who lead a sedentary or "normal" life. You should avoid rapid weight loss, swings in weight, and improper dieting.īMI is solely based on weight and height, so it may be an imprecise indicator (might come out as overweight) of body fat if someone has a large bone structure, athletic build or a large muscle mass. The goal of weight loss should be to improve health. Some research studies have shown that a weight loss of 1 to 2 pounds per week for six months can improve the health of overweight people. This calculator computes appropriately your BMI by using a "redefined overweight and obese BMI thresholds for different gender and age groups", a 2015 study, for people who are more than 16 years old male or female.
BMI is also known as Quetelet’s index.īMI is a way to discover if you are overweight, obese, underweight or normal. For most people, BMI is a good predictor of health problems that are linked to excess weight. BMI is a person's weight in kilograms divided by his/her height in meters squared.
