Enter the amount of coolant the vehicle can hold (L) and the percentage of concentrated coolant desired (%) into the Coolant Ratio Calculator. The calculator will evaluate and display the Coolant Ratio. 

Coolant Ratio Formula

The following formula is used to calculate the Coolant Ratio. 

CLR = AC * C/100
  • Where CLR is the Coolant Ratio (L)
  • AC is the amount of coolant the vehicle can hold (L) 
  • C is the percentage of concentrated coolant desired (%) 

To calculate the coolant ratio, multiply the amount of coolant the vehicle can hold by percent of coolant desired.

How to Calculate Coolant Ratio?

The following example problems outline how to calculate Coolant Ratio.

Example Problem #1:

  1. First, determine the amount of coolant the vehicle can hold (L).
    • The amount of coolant the vehicle can hold (L) is given as: 12.
  2. Next, determine the percentage of concentrated coolant desired (%).
    • The percentage of concentrated coolant desired (%) is provided as: 50.
  3. Finally, calculate the Coolant Ratio using the equation above: 

CLR = AC * %C/100

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

CLR = 12 *50/100 = 6.00 (L)

Example Problem #2: 

For this problem, the variables required are provided below:

amount of coolant the vehicle can hold (L) = 6

percentage of concentrated coolant desired (%) = 30

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

CLR = AC * %C/100 = ?
