Body fat formula for women:

• A1 = Body Weight * 0.732 + 8.987
• A2 = Wrist Measurement At Fullest Point / 3.140
• A3 = Waist Measurement At Navel * 0.157
• A4 = Hip Measurement At Fullest Point * 0.249
• A5 = Forearm Measurement At Fullest Point * 0.434
• B = A1 + A2 - A3 - A4 + A5
• Body Fat = Body Weight - B
• Body Fat Percentage = Body Fat * 100 / Body Weight

Body fat formula for men:

• A1 = Body Weight * 1.082 + 94.42
