Average cost comparison formulas for heating fuels:

Electricity

C_e = p_e (100000 Btu) / (3412 Btu/kWh)  (1)

where 

C_e = electricity cost per 100000 Btu

p_e = electricity price per kWh

Natural Gas 

C_ng = p_ng (100000 Btu) / (1028 Btu/ft³)  (1)

where 

C_ng = natural gas cost per 100000 Btu

p_ng = natural gas price per cubic ft.

Propane LP Gas (Liquid Propane Gas)

C_lp = p_lp (100000 Btu) / (91333 Btu/gallon)  (1)

where 

C_lp = propane gas cost per 100000 Btu

p_lp = propane price per gallon

Fuel Oil

C_fo = p_fo (100000 Btu) / (140000 Btu/gallon)  (1)

where 

C_fo = fuel oil cost per 100000 Btu

p_fo = fuel oil price per gallon
