Metrication or metrification is the act or process of converting to the metric system of measurement. [1] All over the world, countries have transitioned from local and traditional units of measurement to the metric system. This process began in France during the 1790s, and has persistently advanced over two centuries, accumulating into 95% of ...
70.93164 pdl. The kilogram-force (kgf or kgF), or kilopond (kp, from Latin: pondus, lit. 'weight'), is a non-standard gravitational metric unit of force. It is not accepted for use with the International System of Units (SI) [1] and is deprecated for most uses. [citation needed] The kilogram-force is equal to the magnitude of the force exerted ...
The International Prototype of the Kilogram (referred to by metrologists as the IPK or Le Grand K; sometimes called the ur -kilogram, [1][2] or urkilogram, [3] particularly by German-language authors writing in English [3][4]: 30 [5]: 64 ) is an object whose mass was used to define the kilogram from 1889, when it replaced the Kilogramme des ...
The kilogram, symbol kg, is the SI unit of mass. It is defined by taking the fixed numerical value of the Planck constant h to be 6.626 070 15 × 10−34 when expressed in the unit J⋅s, which is equal to kg⋅m 2 ⋅s −1, where the metre and the second are defined in terms of c and ΔνCs. — CGPM [7][8]
For example, 1 m/s = 1 m / (1 s) is the coherent derived unit for velocity. [ 1 ] : 139 With the exception of the kilogram (for which the prefix kilo- is required for a coherent unit), when prefixes are used with the coherent SI units, the resulting units are no longer coherent, because the prefix introduces a numerical factor other than one.
0.224809 lbf. The newton (symbol: N) is the unit of force in the International System of Units (SI). In SI base units, it is defined as , the force which gives a mass of 1 kilogram an acceleration of 1 metre per second squared. It is named after Isaac Newton in recognition of his work on classical mechanics, specifically his second law of motion.

The slug is defined as the amount of mass that accelerates at 1 ft/s 2 when one pound-force is exerted on it, and is equivalent to about 32.2 pounds (mass). The kilogram-force is a non-SI unit of force, defined as the force exerted by a one-kilogram mass in standard Earth gravity (equal to 9.80665 newtons exactly).
