The dyne (symbol: dyn; from Ancient Greek δύναμις (dúnamis) 'power, force') is a derived unit of force specified in the centimetre–gram–second (CGS) system of units, a predecessor of the modern SI.
The centimetre–gram–second system of units (CGS or cgs) is a variant of the metric system based on the centimetre as the unit of length, the gram as the unit of mass, and the second as the unit of time.
2 lip 2024 · The most commonly used unit is the Newton (N), defined as the force necessary to accelerate a one-kilogram mass by one meter per second squared. Other units include the dyne, used in the centimeter-gram- second (CGS) system, where one dyne is the force needed to accelerate a one-gram mass by one centimeter per second squared.
Review SI (metric) and USC (U.S. or British) units of measurement and their proper use. Understand the differences between base and derived units. Know how to convert between different units using conversion factors. Learn about the conventions and accepted practices of using units.
In CGS units, charge is measured in esu, a derived unit defined by Coulomb's law as you've written it. One esu is the charge such that two charged bodies feel the Coulomb force $$F = \frac{Q_1Q_2}{R^2}$$
The SI unit for force comes from Newton’s 2nd law, F = ma, and is the Newton or N. 1 N = 1 kg·m/s2. The cgs unit for force comes from the same equation and is called the dyne, or dyn. 1 dyn = 1 g·cm/s2. dynes are a lot smaller than Newtons: 105 dyn = 1 N.
