Poundal Foot
The poundal foot (pdl*ft) is a unit of energy representing the work done when a force of one poundal acts over a distance of one foot.
History/Origin
The poundal foot originated in the foot-poundal system of units, which was used primarily in the 19th and early 20th centuries in engineering and physics before the widespread adoption of the SI system.
Current Use
The poundal foot is rarely used today and has been largely replaced by the joule in scientific and engineering contexts. It may still appear in historical references or specialized fields dealing with imperial units.
Therm
A therm is a unit of energy used primarily to measure natural gas consumption, equivalent to 100,000 British thermal units (BTUs).
History/Origin
The therm was introduced in the early 20th century by the American Gas Association to standardize natural gas billing and measurement; it became widely adopted in North America for energy calculations.
Current Use
Today, the therm is still used in the natural gas industry for billing and energy measurement, although other units like gigajoules and cubic meters are also common globally.
