About the Fuel Burn Calculator
This page multiplies a user-defined fuel-unit rate by time without assuming a fuel type or aircraft.
Formula
Estimated fuel used = burn rate × time.
Example
12.5 entered units per hour for 4 hours gives 50 entered fuel units.
Notes
No reserves, phases of flight, aircraft data, weather or regulatory requirements are included. This is not fuel-planning guidance.
