In this calculation weâll use an ethane heat content of 66,500 BTU per gallon. The top boxes in Figure #1 show the conversion of the ethane price per gallon to dollars per MMbtu. So if the price of ethane is 22 cents, divide by 66,500 and multiply by 1,000,000 to yield an equivalent gas price of $3.31/MMbtu.
One gigajoule is one billion joules. The amount of natural gas consumed each year in a typical Canadian home is equivalent to 120 gigajoules. One BTU is 1054.615 joules, equivalent to the amount of energy released by completely burning one wooden match. The amount of energy represented by one gigajoule is equivalent to about 30 litres of gasoline, 39 litres of propane, 278 kilowatt-hours of electricity or 45.5 kilograms of coal.
