MMBTU â One million British Thermal Units or BTUs. Natural gas is generally bought and sold in MMBTUs and future prices are generally quoted in this unit of measure. Therm â 1 Therm = 100,000 BTUs. SCF â Standard Cubic Foot is one cubic foot of gas at standard temperature and pressure (60 degrees F and sea level).
For the sake of comparison, one average cubic foot of natural gas about 1,000 BTU's of heat energy.The chart below shows how much heat energy is released in various quantities of natural gas.
