Sthène to Kilogram-force Converter

A sthène (sn) is a unit of force in the metre-tonne-second (MTS) system, equal to 1,000 newtons. It was designed as part of an alternative metric system but never achieved widespread adoption.

The sthène was proposed in the early 20th century as part of the metre-tonne-second system, intended to provide more practical unit sizes for engineering applications. However, it was superseded by the adoption of SI units and never gained significant usage.

Sthènes are obsolete and rarely encountered in modern applications. They appear only in historical engineering literature and some specialized contexts. The unit has been completely replaced by kilonewtons and other SI force units in all practical applications.

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.
