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.
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.
5 cze 2024 · CGS system of units (centimeter-gram-second). In the following text, you will find the definitions and conversion factors of CGS units in mechanics and electromagnetism. We have also prepared the table with commonly used physical constants in CGS units compared to SI units.
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.
26 paź 2003 · When we say, for example, that the dyne is the CGS unit of force, this determines its definition: it is the force which accelerates a mass of one gram at the rate of one centimeter per second per second.
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. Energy. The SI unit for energy is the Joule, or J. 1 J = 1 kg·m2/s2. The cgs unit for energy is the erg. 1 erg = 1 g·cm2/s2. ergs are a lot smaller than Joules; 107 ergs = 1 J.
The cgs Gaussian system is nonetheless commonly used in theoretical physics, while the MKS system (based on the meter, kilogram, and second) is commonly used in engineering and physics instruction. The following table summarizes common quantities and their units in both MKS and cgs.
