Fuel Energy and Range
BTU and kWh from tank and LHV; range from tank * mpg * load factor.
Example
You enter
- Fuel gasoline_E10
- Tank (gal) 18
- MPG 28
- MPG basis fuel gasoline_E10
- Load factor (0-1.5) 1
You get
- Theoretical range 504 mi
- Total (Btu) 2016000
Details, formula, and sources
Energy stored (BTU) = tank_gal × LHV; range = tank × mpg × load_factor for liquid fuels; conversion to kWh via 1 BTU = 0.000293 kWh.
