Average cost comparison formulas for heating fuels:

Electricity

Ce = pe (100000 Btu) / (3412 Btu/kWh)                  (1)

where 

Ce = electricity cost per 100000 Btu

pe = electricity price per kWh

Natural Gas 

Cng = png (100000 Btu) / (1028 Btu/ft3)                 (2)

where 

Cng = natural gas cost per 100000 Btu

png = natural gas price per cubic ft.

Propane LP Gas (Liquid Propane Gas)

Clp = plp (100000 Btu) / (91333 Btu/gallon)                  (3)

where 

Clp = propane gas cost per 100000 Btu

plp = propane price per gallon

Fuel Oil

Cfo = pfo (100000 Btu) / (140000 Btu/gallon)                (4)

where 

Cfo = fuel oil cost per 100000 Btu

pfo = fuel oil price per gallon
