Force Converters

Force is any interaction that, when unopposed, changes the motion of an object — a push or pull described by Newton's second law: force equals mass times acceleration (F = ma). The SI unit is the newton (N), defined as the force needed to accelerate one kilogram at one meter per second squared. Force is often confused with weight and mass: weight is the gravitational force on a mass, and varies with gravity, while mass is constant. Engineers use kilonewtons for structural loads and meganewtons for rocket thrust; physicists use dynes in the CGS system for microscale work; and US engineering practice uses pound-force and kip-force. All force units are interconvertible through their definition relative to the newton.
