## Definition: What is BMI?

Looking at an insurance height-weight chart isn’t enough to figure out how much your adolescent should weigh. It takes into account how much bone, muscle, and fat he or she has. The most important metric to consider is body fat percentage.

The body mass index (BMI) is a decent estimate of how much fat your kid has (BMI). Although it’s not a perfect measurement, it provides a good estimate of how much of your teen’s body is made up of fat.

Adults alone should use the following formulas. The BMI varies by age and gender for children and teens from 2 to 19 years old. Using one of the following formulae, you can calculate your BMI. However, there’s still one more thing you need to do. If your teen’s weight falls inside the BMI-for-age percentile, it means he or she is in the normal range for his or her age and gender group.

## What is the best way to adjust BMI for amputations?

**What is the BMI formula?**

**Step 1:**Compute your estimated body weight. We= W0 (1-P)

**Step 2:**Compute your estimated BMI. Estimated BMI = [estimated body weight (lb)/height (in)^{2}] x 703. Estimated BMI = [We(lb)/height(in)2] x 703.. Estimates of the percentage of total body mass that can be atrophied for common amputation levels were used for P.]

## How to Calculate BMI for Amputee?

Keeping tabs on your body mass index (BMI) is a crucial aspect of maintaining a healthy weight and avoiding health issues like heart disease. You must, however, include the weight of the amputation in your BMI calculation if you’ve had one. Amputees’ body mass index (BMI) may be easily calculated thanks to research conducted by anthropologists.

**Step 1:**The first step is to take a weight measurement and record it.

**Step 2:**Look up your amputation type’s percentage of body weight number on the internet (see Tips). According to this example, the missing limb would account for 16 percent of a man’s total body weight if it were severed.

**Step 3:**Decimalize the number from Step 2 by moving the decimal point two places to the left. The new value, for example, is 0.16.

**Step 4:**Subtract Step 3’s result from 1. For example, 1 – 0.16 Equals 0.84.

**Step 5:**The current weight is divided by the result of step 4. If a man weighs 160 pounds, his weight is equal to 160 divided by 84 cents, or 194.48. Without the amputation, he is projected to weigh this much.

**Step 6:**The calculated total weight should be multiplied by 703. For instance, multiply 194.48 by 703 to get 136719.44.

**Step 7:**Inches, measure the height. As an illustration, a man who is 6 feet 2 inches tall must multiply his height by the 12 inches in one foot, which results in 72 inches, plus an additional 2, for a total height of 74 inches.

**Step 8:**Add together all the inches to get the height in square inches. For example, multiplying 74 by 74 equals 5,476.

**Step 9:**Subtract the result from Step 8 from the result from Step 6. 136719.44 divided by 5476 gives us a value of 24.97. This is the man’s BMI.
