For example, the CGS unit of force is the dyne, which is defined as 1 g⋅cm/s 2, so the SI unit of force, the newton (1 kg⋅m/s 2), is equal to 100 000 dynes. On the other hand, in measurements of electromagnetic phenomena (involving units of charge , electric and magnetic fields, voltage , and so on), converting between CGS and SI is less ...
Once a set of coherent units have been defined, other relationships in physics that use those units will automatically be true—Einstein's mass–energy equation, E = mc 2, does not require extraneous constants when expressed in coherent units. [10] Isaac Asimov wrote, "In the cgs system, a unit force is described as one that will produce an ...
This system is the most common of the several electromagnetic unit systems based on the centimetre–gram–second system of units (CGS). It is also called the Gaussian unit system, Gaussian-cgs units, or often just cgs units. [a] The term "cgs units" is ambiguous and therefore to be avoided if possible: there are several variants of CGS, which ...
While not an SI-unit, the litre may be used with SI units. It is equivalent to (10 cm) 3 = (1 dm) 3 = 10 −3 m 3. Many non-SI units continue to be used in the scientific, technical, and commercial literature. Some units are deeply embedded in history and culture, and their use has not been entirely replaced by their SI alternatives.

Then the formula would be kg = h / 6.626 070 15 × 10 −34 ⋅m 2 ⋅s −1 ampere: Prior (1881): A tenth of the electromagnetic CGS unit of current. The [CGS] electromagnetic unit of current is that current, flowing in an arc 1 cm long of a circle 1 cm in radius, that creates a field of one oersted at the centre. [8] IEC
Originally, many thước of varying lengths were in use in Vietnam, each used for different purposes. According to Hoàng Phê (1988), [1] the traditional system of units had at least two thước of different lengths before 1890, [2] the thước ta (lit. "our ruler") or thước mộc ("wooden ruler"), equal to 0.425 metres (1 ft 4.7 in), and the thước đo vải ("ruler for measuring ...
