Conversion Factors (approximate)

1 tonne crude oil = 7.5 barrels = 1.19 cubic metres;
1 barrel (US) = 35 Imperial gallons = 0.16 cubic metres;
1 cubic metre = 35.31 cubic feet;
1 billion cubic metres of gas = 0.92 million tonnes of oil equivalent;
1 cubic metre of gas = 0.36 therms;
1 tonne fuel oil = 405 therms;
1 therm = 105.5 megajoules (MJ);
1 kilowatt hour = 3.6 megajoules.
1 million tonnes of crude oil = 7.5 million barrels;
1 million tonnes of crude oil per year = 21 thousand barrels per day.
