Fuel Flow Rate Calculator

Turning a Logged Fuel Quantity Into a Rate

If you've measured how much fuel was actually consumed over a known time period — from a meter reading, tank dip, or test run — this calculator converts that into a standard hourly flow rate for comparison against equipment ratings.

The Formula

Worked Example

A tank test shows 340 liters consumed over 8 hours of operation:
