Enter the total fluid mass (g) and the total substance mass (g) into the Fluid Ratio Calculator. The calculator will evaluate and display the Fluid Ratio. 

Fluid Ratio Formula

The following formula is used to calculate the Fluid Ratio. 

FR= F / TM * 100

  • Where FR is the Fluid Ratio (%)
  • F is the total fluid mass (g) 
  • TM is the total substance mass (g) 

How to Calculate Fluid Ratio?

The following example problems outline how to calculate Fluid Ratio.

Example Problem #1:

  1. First, determine the total fluid mass (g). 
    • The total fluid mass (g) is given as: 300.
  2. Next, determine the total substance mass (g). 
    • The total substance mass (g) is provided as: 600.
  3. Finally, calculate the Fluid Ratio using the equation above: 

FR= F / TM * 100

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

FR= 300 / 600 * 100 = 50.00 (%)


Example Problem #2: 

For this problem, the variables required are provided below:

total fluid mass (g) = 600

total substance mass (g) = 800

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

FR= F / TM * 100 = ?
