Lean Body Mass Calculator - Calculatorall.com
This lean body mass calculator can be used for computing an individual's LBM depending on their body weight, gender, age and height. In order to allow you to perform comparisons, the calculator even gives you results calculated according to different formulas.
The lean body mass, basically, refers to the portion of our body composition which is the difference of our total weight of the body and total weight of the fat. While LBM percentage is not calculated normally, it refers to complement of percentage of our total body fat. On average the LBM ranges anywhere between 60-90 percent of total weight of our body. Typically, men tend to have a higher LBM proportion as compared to women. Also, dosages of a few anesthetic agents, especially the drugs that are water-soluble, are based on lean body mass. Several formulas exist for calculation of estimated LBM and this lean body mass calculator uses three different formulas for the calculation of LBM in adults. You can rely on any of the three formulas and decide what your lean body mass is.
Boer Formula:
For Men:
eLBM = 0.407*weight + 0.267*height - 19.2
For Women:
eLBM = 0.252*weight + 0.473*height - 48.3
The Hume Formula:
For Men:
eLBM = 0.32810*weight + 0.33929*height - 29.5336
For Women:
eLBM = 0.29569*weight + 0.41813*height - 43.2933
The James Formula:
For Men:
eLBM = 1.1*weight + 128*(Weight/Height)2
For Woman:
eLBM = 1.07*weight - 148*(Weight/Height)2
Boer Formula:
