Not intended for use outside fields where CGS energy units are standard or required
Frequently Asked Questions
-
What is a foot-pound [ft*lbf] used to measure?
-
A foot-pound measures energy, defined by the work done by one pound-force moving an object one foot in the direction of the force, commonly used in mechanical work and torque.
-
Why convert foot-pounds to ergs?
-
Converting foot-pounds to ergs allows comparison and analysis in scientific fields that use the CGS system, such as astrophysics and classical mechanics.
-
What fields commonly use ergs as an energy unit?
-
Ergs are primarily used in astrophysics, laboratory physics calculations using CGS units, and in historical scientific literature.
