Ounce-force to Kilogram-force Converter

An ounce-force (ozf) is a unit of force equal to the gravitational force exerted by a mass of one ounce under standard Earth gravity. It equals approximately 0.278 newtons, providing fine force measurements in imperial systems.

The ounce-force developed as a subdivision of the pound-force to provide more precise force measurements in imperial systems. It became useful for applications requiring finer force resolution than pound-force could practically provide.

Ounce-force is used in precision applications within imperial systems, small mechanical devices, and applications requiring fine force measurements. It's found in precision instrument specifications, small mechanical systems, and detailed engineering calculations.

A kilogram-force (kgf) is a unit of force equal to the gravitational force exerted by a mass of one kilogram under standard Earth gravity. It equals approximately 9.807 newtons and represents force in terms of familiar weight measurements.

The kilogram-force developed as a practical force unit based on the familiar concept of weight. It was widely used before the adoption of SI units, particularly in countries using the metric system, providing an intuitive way to express forces in terms of equivalent weights.

Kilogram-force is still used in some engineering applications, particularly in countries transitioning to SI units. It's found in some mechanical specifications, older engineering references, and applications where weight-equivalent forces are more intuitive than newtons.
