Fuel Consumption Calculators
Biomass Fuel Consumption Calculator
Calculate biomass fuel feed rate from heat demand, moisture-adjusted heating value, and boiler efficiency.
CNG Consumption Calculator
Calculate compressed natural gas (CNG) fuel needed for a trip using Gasoline Gallon Equivalent (GGE) fuel economy.
Coal Consumption Calculator
Calculate the amount of coal needed to generate a target energy output based on plant efficiency and coal heating value.
Diesel Consumption Calculator
Calculate diesel fuel consumption from engine power output and specific fuel consumption (SFC).
Ethanol Fuel Consumption Calculator
Calculate real-world fuel consumption for ethanol-blended fuel (E10, E85) accounting for ethanol's lower energy content.
Fuel Consumption Calculator
Calculate fuel consumption rate from heat input and fuel heating value. Works for any fuel with a known heating value.
Fuel Cost Per Mile Calculator
Calculate the true fuel cost per mile driven based on fuel price per gallon and vehicle fuel economy (MPG).
Fuel Flow Rate Calculator
Calculate fuel flow rate from total fuel quantity consumed over a measured time period.
Fuel Mass Flow Calculator
Convert fuel volumetric flow rate into mass flow rate using fuel density.
Fuel Volume Flow Calculator
Convert fuel mass flow rate into volumetric flow rate using fuel density.
Generator Fuel Consumption Calculator
Calculate generator fuel consumption based on rated power, actual load percentage, run hours, and fuel consumption rate.
Heating Oil Consumption Calculator
Calculate heating oil consumption in liters per hour from heat input, boiler efficiency, and oil heating value.
Hydrogen Fuel Consumption Calculator
Calculate hydrogen fuel needed for a trip in a fuel cell electric vehicle based on miles-per-kilogram fuel economy.
Idle Fuel Consumption Calculator
Calculate annual fuel wasted from vehicle idling based on daily idle time and idle fuel consumption rate.
Jet Fuel Consumption Calculator
Calculate total jet fuel consumed on a flight based on fuel burn rate and flight time.
Kerosene Heater Fuel Consumption Calculator
Calculate kerosene fuel needed to run a heater for a given output and duration based on kerosene's energy content.
LPG Consumption Calculator
Calculate LPG consumption in kilograms per hour from heat input and LPG heating value.
Marine Fuel Consumption Calculator
Calculate total marine fuel consumption for a voyage using Specific Fuel Oil Consumption (SFOC), engine power, and voyage duration.
Natural Gas Consumption Calculator
Calculate natural gas consumption in cubic meters per hour from heat input and gas heating value.
Propane Consumption Calculator
Calculate propane consumption in kilograms per hour from heat input and propane heating value.
Not All Fuels Pack the Same Punch
Comparing fuel costs or consumption rates only makes sense once you account for how much usable energy each fuel actually contains per gallon, cubic foot, or kilogram — a number that varies significantly across fuel types. These ten calculators cover consumption and flow rate math for common fuels.
