The thrust of a rocket engine, for example, was measured in kilograms-force in 1940s Germany, in the Soviet Union (where it remained the primary unit for thrust in the Russian space program until at least the late 1980s), and it is still used today in China and sometimes by the European Space Agency.
Kraften fra en raketmotor blev f.eks. målt i kilopond i Tyskland, i Sovjetunionen (hvor den forblev den primære enhed i det sovjetiske rumprogram indtil sidst i 1980'erne), og anvendes stadig i Kina og til tider af European Space Agency.
