The kilogram-force has never been a part of the International System of Units (SI), which was introduced in 1960. But my general point is that this is useful wherever something is both proportional to mass and distance(/displacement). As an example of momentum, consider a rocket ship coasting through space at a speed v of 10,000 (10 4 ) m/s.

In 1791, the French parliament imposed the use of the metric system on the country, and it is now used in Continental Europe and many other parts of the world. Since multiplication is commutative and associative with units, there are often many equally valid intuitive models for a given combination of units. The kilogram-metre (or more often the kilogram-kilometre) is a unit of measurement indicating that 1 kg (lets assume of coal) has been moved 1 km (towards, for example, a power station). Open Shortest Path First, often shortened to OSPF, is an IP routing protocol used to find the best path to distribute packets as . To take a deliberately non-physics example, a difficult task might need either many people to work on it or people to work on it for a long time, so its difficulty is proportional to both the number of workers and the time spent and could thus be measured in "person-days".

In 1940s, Germany, the thrust of a rocket engine was measured in kilograms-force, [ citation needed] in the Soviet Union it remained the primary unit for thrust in the Russian space program until at least the late 1980s. It explained why radioactive materials don't 'melt' while emitting streams of particles (it is because of the extreme efficiency of converting mass to energy). When looking at it that way you could think about multiplied units as conserved quantities, if you would double one you should half the other to have the same effect. If we defined the coulomb and the volt as base units, we would be perfectly happy to define our unit of energy as a coulomb volt. Their basic unit of weight was the 'uncia,' from which the English word 'ounce' is originally derived.

Multiplied units often turn up in "double proportion" situations, where a particular quantity is proportional to multiple dependent variables. s 2 for this purpose in 1901, [5] though they had been used in low-precision measurements of force before that time. Moving to a fairly exact parallel from a physics context, an electron-volt - or, to be pedantic, an electron-charge-volt - is a good unit of energy because the work done to move a charge through a potential difference is proportional to both the charge and the potential difference. Of course you need to include the gravitational acceleration with its proper units to compare to any other form of energy.In 1795 metric measurement systems were introduced in France and the gram was defined as "the absolute weight of a volume of pure water equal to a cube of one hundredth of a metre, and at the temperature of the melting ice". It meant that the law of conservation of energy (it says that the sum of potential energy and kinetic energy of a body is constant) and the law of conservation of mass are, in fact, the same.
