Is Natural Gas hard to measure?
Natural gas is measured and sold in cubic feet, or in British Thermal Units (heat content). Basically, heat from energy sources can be measured and converted back and forth between British thermal units (or Btu for short) and metric units. One Btu is the heat required to raise the temperature of one pound of water by 1 degree. For example, one match can release 1 Btu. A chocolate bar has about 1000 Btu. What is it used for? It can be used for many things. One of its more common uses is for heating. It is also used in anti-freeze, plastics, dye and paints. Compressed natural gas has also been used to fuel cars. Natural gas burns cleaner than coal or oil, and produces less greenhouse emissions.
