Enter the total amount of rice used (cups) into the Rice to Water Ratio Calculator. The calculator will evaluate and display the amount of water needed.

Rice to Water Ratio Formula

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

RTW = R * 2
  • Where RTW is the Rice to Water Ratio (cups of water needed)
  • R is the total amount of rice used (cups) 

To calculate the rice to water ratio, multiply the amount of rice used by 2.

How to Calculate Rice to Water Ratio?

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

Example Problem #1:

  1. First, determine the total amount of rice used (cups).
    • The total amount of rice used (cups) is given as: 4.
  2. Finally, calculate the Rice to Water Ratio using the equation above: 

RTW = R * 2

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

RTW = 4 * 2 = 8 (cups of water needed)


Example Problem #2: 

For this problem, the variables required are provided below:

total amount of rice used (cups) = 8

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

RTW = R * 2 = ?
