An easy way to calculate the body fat percentage

Try calculating your body fat percentage with below formula. This formula is not applicable for bodybuilders and pregnant women.

1 Feet = 30.48 cm
1 Inch =2.54 cm

Example for Male:

Height – 5 feet 8 inches

Weight – 80 kg

Convert height from inches to centimeters for further calculation

5 x 30.48    = 152.4 cm

8 x 2.54    = 20.32 cm

Total               172.72 = 173cm (height)

Step 1:

Find ideal body weight according to the height.

173 – 100 = 73 kg (100 is ideal weight for male)

Step 2:

Find out overweight or underweight.

Current body weight – IBW

80 – 73 = 7 kg (the individual is overweight with 7 kg)

Step 3:

Fat% – 15 + 7 = 22%

For reference: (15 is an ideal body fat percentage for males)

If the individual is underweight, then also you need to add it with 15 to find the fat percentage.

Example for Female:

Height – 5 feet 5 inches

Weight – 56 kg

Convert height from inches to centimeters for further calculation

5 x 30.48    = 152.4 cm

5 x 2.54    = 12.7 cm

Total        165.1 = 165cm (height)

Step 1:

Find ideal body weight according to the height

165 – 105 = 60 kg (105 is ideal weight for female)

Step 2:

Find out overweight or underweight.

Current body weight – IBW

56 – 60 = – 4 kg (the female is underweight with 4 kg)

Fat% – 20 + 4 = 24%

For reference: (20 is an ideal body fat percentage for females)

If the woman is overweight, add it with 20 to find the fat percentage.

Point 4: Waist measurement (at naval) x 0.157

Thin Body Mass    Point 1 + Point 2 – Point 3 – Points 4 + Point 5

The weight of Body Fat     Total weight of body – Thin Body Mass
