Aircraft fuel burn rate varies enormously by type and flight phase - this calculator estimates total fuel consumed over a flight from a given hourly burn rate and total flight time.
Total Fuel = Burn Rate x Flight Time
Example
A burn rate of 2,500 kg/hour over a 3-hour flight:
Total Fuel = 2,500 x 3 = 7,500 kg (approximately 9,375 liters)
Why Jet Fuel Is Measured by Mass
Jet fuel is conventionally loaded and tracked by mass (kilograms or pounds) rather than volume, since fuel density changes with temperature - and precise mass figures matter directly for aircraft weight and balance calculations that affect performance and safety margins on every flight.
Burn Rate Varies Dramatically by Aircraft
Small regional jets might burn a few hundred kg/hour, while large wide-body aircraft on long-haul routes can burn well over 10,000 kg/hour - burn rate also varies significantly by flight phase, with climb consuming fuel considerably faster than steady cruise, which is why real flight planning uses detailed phase-by-phase fuel calculations rather than a single flat hourly rate.
