One thousand billion cubic feet
First period of the Mesozoic era of geologic time, from 245 to 208 million years ago
MWt refers to thermal output from a reactor or heat source (eg the gross heat output of a reactor itself, typically three times the MWe figure).
In order to be able to compare different primary sources of energy such as oil, natural gas and coal they are often converted into their equivalent to one ton of oil in order to be able to compare like with like
The quantity of natural gas occupying a volume of one thousand cubic feet at a temperature of sixty degrees Fahrenheit and at a pressure of 14.73 PSIA (PSI absolute)
An imperial unit of energy largely replaced by the metric equivalent equal to 29.3071 kilowatt hours or 100,000 btu or 29.3071 KWH. If one had the price of natural gas in therm and one wants to convert it to the price per mmbtu one needs to multiply by 10 (50 cents per therm = $5 mmbtu).
If one has the price of natural gas in pence per therm and one wants to convert it to $/mmbtu, this is equivalent to $0.1565 per mmbtu. Thus a natural gas price of 22 pence a therm would be equal to $3.44 mmbtu
Rocks from the Tertiary era that were formed between 65 and 1.8 million years ago
