Enter the fuel load (gallons) and the fuel rate (gallons/hr) into the Calculator. The calculator will evaluate the Fuel Time. 

Fuel Time Formula

FT = FL / FR


  • FT is the Fuel Time (hours)
  • FL is the fuel load (gallons)
  • FR is the fuel rate (gallons/hr)

To calculate Fuel Time, divide the fuel load by the fueling rate.

How to Calculate Fuel Time?

The following steps outline how to calculate the Fuel Time.

  1. First, determine the fuel load (gallons). 
  2. Next, determine the fuel rate (gallons/hr). 
  3. Next, gather the formula from above = FT = FL / FR.
  4. Finally, calculate the Fuel Time.
  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.

fuel load (gallons) = 577

fuel rate (gallons/hr) = 1234
