Meganewton to Sthène Converter

A meganewton (MN) is a unit of force equal to one million newtons. It represents extremely large forces typically encountered in large-scale engineering applications, geological processes, and major structural systems.

The meganewton emerged as a practical unit with the development of large-scale civil engineering projects and heavy industry in the 20th century. It became necessary for describing forces in major bridges, skyscrapers, large machinery, and geological phenomena where smaller units would result in unwieldy numbers.

Meganewtons are used in civil engineering for major structural analysis, aerospace engineering for rocket thrust, heavy machinery design, and geological studies. They're standard for describing forces in large bridges, building foundations, mining equipment, and tectonic processes.

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 However, it was superseded by the adoption of SI units and never gained significant usage.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.
