Gallons Per Hour Consumption Calculation

This calculator is used to calculate the Gallons Per Hour (GPH) Consumption Rate for AvGas and Jet A.All entries should be numeric and may be decimal if needed. Enter time values as hours; 6 minutes is 1/10 hour. Enter fuel values in gallons. The answers are returned as calculated values, based on your entries.

Fuel Consumption Calculator

  • Enter Fuel Capacity In Gallons For All Tanks

  • Enter Trip Time Elapsed In Hours

  • Enter Starting Fuel In Gallons In All Tanks

  • Enter Ending Fuel In Gallons In All Tanks

  • Calculated Gallons Per Hour (GPH) Consumption Rate

  • Calculated Fuel (Gallons)

  • Your Trip Start Fuel Load (Gallons)

  • Full Fuel Load Potential (Hours)

  • Trip Start Fuel (AvGas) Load Weight (Pounds)

  • Trip Start Fuel (Jet A) Load Weight (Pounds)


Aviation Gasoline weight per gallon(gw)=6.00
Jet A weight per gallon(dw)=6.84
Total Capacity (AvGas) Fuel Load Weight=(Fuel weight)* (gw)
GPH=start fuel-end fuel

Be sure to take into consideration winds aloft, restricted zones, climb time and fuel for a margin of safety when calculating requirements. Be sure to check the current NOAA aviation weather for departure, along the flight plan and at the destination airport before departure. Free online Mechanical engineering Calculators.
