Electricity

Electric Demand/Capacity is measured in terms of WATTS. WATT (Power) Amps (current) X Voltage 1,000 WATTS (W) 1 Kilowatt (kW) 1,000 Kilowatts 1 Megawatt (MW)

Electric Energy is measured in terms of WATT‐HOURS. 1 kilowatt hour (Kwh) 3,412 Btu (100 watt light bulb burning for 10 hours would use 1 kilowatt‐hour of electricity) 1 megawatt hour (Mwh) 1,000 Kwh

Natural Gas to Oil

1 therm .72103 gallons distillate/.668045 gallons residual 1 Mcf 7.366 gallons distillate/6.834 gallons residual

Oil to Natural Gas

1 gallon distillate 1.3869 therms (Heating oils & diesel) 1 gallon residual 1.4969 therms (#6 oil)

Heat Content for Oil

1 barrel (42 gallons) distillate 5,825,000 Btu 1 barrel (42 gallons) residual 6,287,000 Btu

Coal

To Convert Coal: To: Multiply By: Short or Net Tons (2,000 lbs.) Metric Tons 0.907185 Short or Net Tons (2,000 lbs.) Long Tons 0.892857 Short or Net Tons (2,000 lbs.) Pounds 2,000 Short Tons of Coal Equivalent BTUs 25,198,000 Metric Tons (2,240 lbs.) Short or Net Tons 1.10231 Metric Tons (2,240 lbs.) Long Tons 0.984207 Metric Tons of Coal Equivalent BTUs 27,776,000 Kilograms Pounds 2.205 Pounds Kilograms 2.2046

Short Ton Equals 2,000 Kilowatt hours of electricity (approximately) 1,000 KWH Equals A half ton of coal (approximately)
