Ounce-force to Poundal 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 poundal (pdl) is a unit of force in the foot-pound-second (FPS) system, defined as the force required to accelerate a mass of one pound at a rate of one foot per second squared. It equals approximately 0.138 newtons.

The poundal was introduced in 1879 as part of the foot-pound-second system to provide a force unit based on fundamental physical principles rather than gravitational force. It was designed to be the imperial equivalent of the newton but never achieved widespread adoption.

Poundals are rarely used in modern applications, appearing mainly in historical engineering literature and some specialized physics contexts. They've been largely replaced by pound-force in practical applications and newtons in scientific work.
