Enter the total amount of water consumed (L) and the total body weight (lbs) into the Water to Weight Ratio Calculator. The calculator will evaluate and display the Water to Weight Ratio. 

Water to Weight Ratio Formula

The following formula is used to calculate the Water to Weight Ratio. 

WWR = WA / WG
  • Where WWR is the Water to Weight Ratio (water:weight)
  • WA is the total amount of water consumed (L) 
  • WG is the total body weight (lbs) 

To calculate the water-to-weight ratio, divide the amount of water consumed by the body weight.

How to Calculate Water to Weight Ratio?

The following example problems outline how to calculate Water to Weight Ratio.

Example Problem #1:

  1. First, determine the total amount of water consumed (L).
    • The total amount of water consumed (L) is given as: 4.
  2. Next, determine the total body weight (lbs).
    • The total body weight (lbs) is provided as: 200.
  3. Finally, calculate the Water to Weight Ratio using the equation above: 

WWR = WA / WG

The values given above are inserted into the equation below and the solution is calculated:

WWR = 4 / 200 = 1:50 (water:weight)


Example Problem #2: 

For this problem, the variables required are provided below:

total amount of water consumed (L) = 5

total body weight (lbs) = 215

Test your knowledge using the equation and check your answer with the calculator above.

WWR = WA / WG = ?
