kilonewton

The kilonewton (symbol kN) is a unit of force in the International System of Units (SI). It equals 1000 newtons, where the newton is the SI unit of force defined as the force required to accelerate a one-kilogram mass at 1 meter per second squared. The kilonewton is a commonly used unit in engineering to express forces that are large but not enormous, such as loads, thrust, or structural reactions.

One kilonewton equals 1000 newtons. In terms of other units, 1 N ≈ 0.1019716 kilogram-force (kgf) under

When expressing mass as weight, it is important to distinguish between kilograms as a unit of mass
