BF\% = 86.010 \times \log_{10}(waist - neck) - 70.041 \times \log_{10}(height) + 36.76
BF% = 86.010×log10(waist-neck) - 70.041×log10(height) + 36.76它计算什么

工作示例
1
86.010 × log10(85-38) = 86.010 × log10(47) = 86.010 × 1.672 = 143.92
70.041 × log10(178) = 70.041 × 2.250 = 157.63
BF% = 143.9 - 157.6 + 36.76 = 23.1%结果: ~23.1%
