Frequently Asked Questions
-
What does one poundal foot represent?
-
One poundal foot is the work done by a force of one poundal moving an object one foot, representing a unit of energy in the FPS system.
-
Why convert poundal foot to Btu (th)?
-
This conversion helps relate classical mechanical energy values to thermal energy units used in heating, cooling, and fuel energy applications.
-
Is the Btu (th) used for measuring heat content?
-
Yes, the Btu (th) is a thermochemical British thermal unit representing heat energy required to raise one pound of water by one degree Fahrenheit.
