F100 jet engine are both around 130 kN. One kilonewton, 1 kN, is equivalent to , or about 100 kg of load under Earth gravity. 1 kN = 102 kg × 9.81 m/s2. So for example, a platform that shows it is rated at will safely support a load. Specifications in kilonewtons are common in safety specifications for: the holding values of fasteners, Earth anchors, and other items used in the building industry; working loads in tension and in shear; rock-climbing equipment; thrust of rocket engines, Jet engines and launch vehicles; clamping forces of the various moulds in injection-moulding machines used to manufacture plastic parts.
