Electricity

 
3413 Btu / kWh
1 kW = 1000 W = 3413 Btu
1 HP = 0.746 kW = 2545 Btu/hr
kW = Volts x Amps x P.F/1000 (P.F = 0 to 1)
kW (3 phase) = Volts x Amps x 1.732 x P.F/1000
C.O.P = Btu cooling / Btu input
EER = Btu cooling / electric input watts
 

Natural Gas

 
1030 Btu / cu. ft.
1 CF = 1000 Btu = 1 MBF
1 CCF = 100 CF = 100,000 Btu = 1 Therm
1 MCF = 1000 CF = 1,000,000 Btu = 1 DecaTherm

Oil

 
#2 Oil...138,500 Btu / gal
#4 Oil...145,000 Btu / gal
#6 Oil...150,000 Btu / gal
Gasoline...125,000 Btu / gal
Propane...91,500 Btu / gal
1 Barrel oil = 42 gal

Carbon Emmisions by Fuel

 
Electric...1 metric ton of CO2 = (kWh * .7)/1000
Natural Gas...1 metric ton of CO2 = ((Therm/9.480) * 52)/1000
#2 Oil...1 metric ton of CO2 = (Gal * 9.84)/1000
Heavy Oils...1 metric ton of CO2 = Bbl * .43
Propane...1 metric ton of CO2 = (Gal * 12.669)/2205
Gasoline...1 metric ton of CO2 = (Gal * 19.4)/2205
Steam...1 metric ton of CO2 = Mlbs * .92356
