Body fat percent Calculator

Use this calculator to estimate the percentage of frame fats you've got compared on your general frame weight. The calculator makes use of unique methods that we are going to mention below for calculating the percentage of frame fats (BF). it's far an immediate manner to get a fashionable concept about the extra flab (fat) your frame incorporates.

How to Use the Calculator to locate frame fats %?

Input (Required):

  • pick a dimension approach
  • upload the values as a result
  • click on the given “Calculate” button

Output (Calculated):

  • body fat percentage
  • fat Mass (all the fats in your frame)
  • Lean Mass (mass of body aside from frame fats)
  • frame fat percent Chart (show the variety wherein your frame falls in)
  • different parameters (BAI, frame fats according to U.S. navy, army, marine and many others.) according to the chosen approach

How to measure body fats percentage?

There are multiple ways to measure frame fats percentage, and every approach varies in accuracy and convenience. you may use traditional formulas or leverage superior frame fat calculators for specific readings.

Body fat percent components:

body fat percent is calculated as the total fat mass divided by way of the overall body mass, then extended by a hundred to explicit it as a percent.

BFP = (Mass of Fat / Body Mass) * 100

Alternative techniques to measure frame fat percent:

Diverse methods can be used to estimate body fats, and a few are greater appropriate for positive people. beneath are a few popular methods for frame fat dimension, such as the one used by our body fat calculator.

1. Circumference measurement

Body circumference measurements help estimate body fat percentage by measuring specific body parts like the waist, hips, and neck. This method requires a non-stretchable measuring tape.

1.1 - U.S. Navy Method:

This method, developed by the U.S. Navy's Naval Health Research Center, is designed for military personnel but can be used by anyone. The following steps are required:

  • For men, measure the waist at the belly button level, for women, measure the waist at the narrowest point.
  • Measure the circumference of the neck just below the larynx.
  • For women, measure the hips at the widest horizontal point.

Female Formula:

Body Fat % = 163.205 * log10(Waist + Hips - Neck) - 97.684 * log10(Height) + 78.387

Male Formula:

Body Fat % = 86.010 * log10(Waist - Neck) - 70.041 * log10(Height) + 36.76

Accuracy: 3.5%

1.2 - Parrillo (Fat Caliper Method)

The Parrillo method, designed by bodybuilding coach John Parrillo, involves measuring body fat at multiple sites. The formula uses the sum of skinfold measurements from 9 sites.

  • Chest
  • Abdominal
  • Thigh
  • Bicep
  • Tricep
  • Subscapular
  • Supra iliac
  • Lower back
  • Calf

Formula:

Body Fat Percentage = (27 * Sum of Skinfold Sites) / Body Weight (lb)

Accuracy: 2.0%

2. Skinfold Measurement

Skinfold measurements were developed by researchers Dr. Andrew Jackson and M.L. Pollock in 1978. These measurements use skinfold calipers to estimate body fat at different sites of the body.

2.1 - Jackson Pollock 7-Point Test

This method requires measurements at seven different sites:

  • Pectoral
  • Abdominal
  • Thigh
  • Triceps
  • Subscapular
  • Supra iliac
  • Midaxillary

For Women:

Body Density = 1.097 - (0.00046971 * Sum of Skinfolds) + (0.00000056 * Sum of Skinfolds^2) - (0.00012828 * Age)

Body Fat Percentage = 495 / Body Density - 450

For Men:

Body Density = 1.112 - (0.00043499 * Sum of Skinfolds) + (0.00000055 * Sum of Skinfolds^2) - (0.00028826 * Age)

Body Fat Percentage = 495 / Body Density - 450

2.2 - Jackson Pollock 4-Point Test

This test uses skinfold measurements from four key sites:

  • Triceps
  • Thigh
  • Supra iliac
  • Abdominal

For Women:

Body Density = (0.29669 * Sum of Skinfolds) - (0.00043 * Sum of Skinfolds^2) + (0.02963 * Age) + 1.4072

Body Fat Percentage = 495 / Body Density - 450

For Men:

Body Density = (0.29288 * Sum of Skinfolds) - (0.0005 * Sum of Skinfolds^2) + (0.15845 * Age) - 5.76377

Body Fat Percentage = 495 / Body Density - 450

2.3 - Jackson Pollock 3-Point Test

This test uses measurements from three key areas:

  • For Women: Triceps, Thigh, Supra iliac
  • For Men: Pectoral, Abdominal, Thigh

For Women:

Body Density = 1.0994921 - (0.0009929 * Sum of Skinfolds) + (0.0000023 * Sum of Skinfolds^2) - (0.0001392 * Age)

Body Fat Percentage = 495 / Body Density - 450

For Men:

Body Density = 1.10938 - (0.0008267 * Sum of Skinfolds) + (0.0000016 * Sum of Skinfolds^2) - (0.0002574 * Age)

Body Fat Percentage = 495 / Body Density - 450

2.4 - Durnin/Womersley Method

This method involves skinfold measurements at four sites:

  • Bicep
  • Tricep
  • Subscapular
  • Supra iliac

For Women:

Body Density = 1.1599 - (0.0717 * log(Sum of Skinfolds))

Body Fat Percentage = 495 / Body Density - 450

For Men:

Body Density = 1.1631 - (0.0632 * log(Sum of Skinfolds))

Body Fat Percentage = 495 / Body Density - 450

Accuracy: 3.5% to 5% depending on the method used.
