Body Fat Percentage Calculator

The body fat percentage calculator is supplied as part of the PowerCalc Cyclists Power Calculator v2.4 onwards.

Estimates riders body fat percentage based on DoDI 1308.3 guidelines. Units for abdomen/waist, neck, hip and height are inches although you can enter your measurements in centimetres if you want to.

Males
percentage body fat = 86.010 * log10(abdomen-neck)- 70.041 * log10(height) + 36.76
Females
percentage body fat = 163.205 * log10(waist+hip-neck) - 97.684 * log10(height)-78.387

Some extra boxes for hip measurements will appear when the calculator is in female mode

These formula attempt to address the problems with using body mass index (BMI). Claimed accuracy is plus or minus one percent. Further information can be found in the PowerCalc help file (press F1 key) and a full copy of DoDi 1308.3 can be downloaded from www.dtic.mil/whs/directives/ corres/pdf/i13083_110502/i13083p.pdf
