Definition
Decatherm
A therm factor is used by gas companies to convert the volume of gas used to its heat equivalent, and thus calculate the actual energy use. The therm factor is usually in the units therms/Ccf. It will vary with the mix of hydrocarbons in the natural gas. Natural gas with a higher than average concentration of ethane, propane or butane will have a higher therm factor. Impurities, such as carbon dioxide or nitrogen lower the therm factor.<p> <p> Ten therms are a decatherm - Dth<p> Thousand decatherms - MDth<p> One million decatherms - MMDth
