Useful Conversion Factors For Energy Saving And CO2 Generation

A small selection of conversion factors that I find useful as part of the project to reduce energy consumption and CO2 emissions.:

CO2 Generation

 

Using 1 KiloWatt Hour of electricity generates 0.43 Kg CO2

These figures are approximations since the actual value depends on the efficiency of the transmission system and the mix of generation types in the case of electricity and the efficiency of the burning process in the case of oil and gas. Utility companies often provide a CO2 figure for their gas and electricity which is more accurate.

Burning 1 Litre of Heating Oil generates 2.68 Kg CO2

Using 1 KiloWatt Hour of gas generates 0.18 Kg CO2

Using 1 Therm (100 Cubic Feet) of Natural Gas generates 5.5 Kg CO2

I Cubic Metre of Natural Gas generates 1.9 Kg of CO2

 
   

Electrical

 

1 KiloWatt Hour = 1000 Watts for 1 hour

1 Watt for 1 hour = 0.001 KiloWatt Hours

   

Gas

 

100 Cubic Feet = 2.83 Cubic Metres of Natural Gas

 

1 Therm = 100 Cubic Feet of Natural Gas

 

   

Heating

 

1 BTU (British Thermal Unit) = 0.29291154 KW

1 KW = 3414 BTU

(Temp in Fahrenheit -32 ) x 0.55555 = Temp in Centigrade

(Temp in Centigrade * 1.8 ) + 32 = Temp in Fahrenheit

   

Water

 

1 bar = 14.5 pounds per square inch

1 pound per square inch = 0.0690 bar

1 centimetre = 0.3937 inches

1 inch = 2.54 centimetres

1 cubic metre = 1000 litres

1 litre = 0.001 cubic metres

1 litre = 0.2193 gallons

1 gallon = 4.5609 litres

   

Weight

 

1000 Kgm = 0.9842064393 Ton

1 Ton = 1016.047 Kgm

1 Kgm = 0.45359237 lb (pounds)

1 lb (pound) = 2.2046226216 Kgm
