Enter the total lean muscle (lbs) and the total bone weight (lbs) into the Calculator. The calculator will evaluate the Muscle To Bone Ratio. 

Muscle To Bone Ratio Formula

MBR = M / B


  • MBR is the Muscle To Bone Ratio (lbs/lbs)
  • M is the total lean muscle (lbs)
  • B is the total bone weight (lbs)

To calculate Muscle To Bone Ratio, divide the total lean muscle by the total bone weight.

How to Calculate Muscle To Bone Ratio?

The following steps outline how to calculate the Muscle To Bone Ratio.

  1. First, determine the total lean muscle (lbs). 
  2. Next, determine the total bone weight (lbs). 
  3. Next, gather the formula from above = MBR = M / B.
  4. Finally, calculate the Muscle To Bone Ratio.
  5. After inserting the variables and calculating the result, check your answer with the calculator above.

Example Problem : 

Use the following variables as an example problem to test your knowledge.

total lean muscle (lbs) = 50

total bone weight (lbs) = 40
