Body mass index (BMI) is a simple calculation based on your height and weight that is used to check for obesity. A BMI of 18.5 to 24.9 signifies a normal weight for your height, according to the Centers for Disease Control and Prevention. The formula, on the other hand, does not take into account your bodily makeup. Because muscle is denser than fat, athletes with a large amount of muscle frequently have a BMI that defines them as overweight.
Multiply the number of feet tall you are by 12 to get your height in inches. For instance, if you’re 5 feet and 10 inches tall, you’d multiply 5 by 12 to get 60 and then add 10 to obtain 70 inches.
Things you Need To Know
In some classes, not all of the students receive the same grade. Some assignments carry more weight in determining your final mark than others. You’ll need to know the weight of each grade to conduct this calculation. This is the proportion of your final grade that the grade counts toward. Your overall grade is calculated by adding all of your weighted assignments together.
1. Determine Grade and Weight
Determine the weight of each grade and your grade on each assignment. Assume you get an 85 percent on a project that accounts for 20% of your final grade and a 100 on a test that accounts for 80% of your final grade.
2. Multiply Grade by Weight
Multiply the assignment grade by the grade weight. In this case, 85 multiplied by 20% equals 17 and 100 multiplied by 80% equals 80.
3. Add together
To get your total grade, add all of your weighted grades together. 17 points plus 80 points yields a weighted grade of 97 in this case.
4. Calculate your grade online
You have to need measurement to calculate your grade in the BMI finder. Enter your information correctly. And get your desired results.
Formulas Used to Calculate BMI
BMI is computed by multiplying the weight by height squared. It’s a straightforward calculation of body weight in relation to height. The following formulas apply to both the metric and US customary units or imperial systems of measurement:
SI (metric) units
BMI=weight(kg) / (height(m))2

The table below applies to anyone over the age of 18. These limits do not alter with age and apply equally to men and women. Body Mass Index as an Obesity Measure – NHS, Body Mass Index, and Health – USDA
Note: Children’s BMI is not calculated in the same way as adults’ BMI. Because the association between fatness and BMI varies by age and gender in children, definitions of obesity and overweight must account for these two variables.
- BMI below 16.0 Kg/m2 Severely underweight
- BMI=16.0 to 18.5 Kg/m2 Underweight
- BMI=18.5 to 24.9 Kg/m2 Normal weight
- BMI=25 to 29.9 Kg/m2 Overweight
- BMI of 30 or greater Kg/m2 Obese
Excess body fat is linked to an increased risk of obesity-related illness in the future. You should also take your waist circumference and skin thickness measures. All of these are indicators of a person’s weight or body fatness.
