What is ounce-force used for?

Ounce-force is typically used to specify small actuation or push forces for switches, keys, and buttons, as well as rating small springs and clips.

Why use gram-force instead of ounce-force?

Gram-force expresses very small forces with finer granularity, making it useful for precision engineering, testing, and calibration applications.

Are these units based on standard gravity?

Yes, both units assume standard gravity (9.80665 m/s²), so variations in local gravity may affect the accuracy of conversions.

Key Terminology

Ounce-force (ozf): A non-SI unit of force equal to one sixteenth of a pound-force, representing the weight of an avoirdupois ounce under standard gravity.
Gram-force (gf): A non-SI unit of force equal to the force exerted by a one gram mass under standard gravity, used to express very small forces.
Standard Gravity: The acceleration due to gravity standardized at 9.80665 m/s², used as a basis for defining these force units.
