Ounce-force inch is a non-SI unit mainly for small torques; resulting kilojoule values can be very small
-
Conversions may need high-precision instruments for accurate usage
-
Small numerical values require careful unit handling to prevent errors
Frequently Asked Questions
-
What does ounce-force inch represent?
-
It is a non-SI unit of energy or torque equal to the moment by one avoirdupois ounce acting through a one-inch lever arm.
-
Why convert ounce-force inch to kilojoule?
-
The conversion expresses small mechanical work or torque in a standard SI energy unit for clarity in scientific and engineering contexts.
-
Is kilojoule used outside of engineering?
-
Yes, kilojoule is widely used in nutrition for reporting dietary energy and in chemical thermodynamics for reaction enthalpies.
Key Terminology
-
Ounce-force inch [ozf·in]
-
