Ounce-force to Pound-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 pound-force (lbf) is a unit of force equal to the gravitational force exerted by a mass of one pound under standard Earth gravity. It equals approximately 4.448 newtons and is one of the most common force units in imperial systems.

The pound-force developed from the traditional English pound weight and became standardized for force measurements in countries using imperial units. It provided a practical force unit based on familiar weight measurements, becoming essential in American engineering and industry.

Pound-force is extensively used in the United States for engineering calculations, mechanical specifications, and force measurements. It's standard for bolt torque specifications, mechanical system ratings, material testing, and general engineering applications in imperial systems.
