Frequently Asked Questions
-
What is a pound-force foot in terms of energy?
-
It is the energy equivalent to a one pound-force acting through a displacement of one foot in the force direction.
-
Why convert pound-force foot to millijoule?
-
To translate mechanical energy from imperial units into the small-scale SI unit for precise scientific and engineering calculations.
-
Are pound-force foot and torque the same?
-
No. Though they share units, torque is a distinct physical quantity and should be interpreted separately from energy.
Key Terminology
-
Pound-force foot [lbf*ft]
-
An imperial unit representing the energy resulting from a one pound-force applied over a one foot displacement.
-
Millijoule [mJ]
-
An SI derived unit of energy equal to one thousandth of a joule, used for measuring small energy amounts.
-
Torque
-
A physical quantity sharing units with energy in pound-force foot but distinct, representing rotational force rather than work.
