Units, Dimensions and Dimensional Analysis
... This is because that separate from the idea of units a measurement has associated with it a quality called dimension. Although we can’t compare areas and lengths we know that they are related by the fact that the area of a square is given by the length of its side squared. We also know that the volu ...

Atomic Units
... A note on Units You may have taken another theory course at some point, where “theory units” were used, that appeared to set all the fundamental constants equal to one. However, since the fine structure constant is always α = e2 /h̄c = 1/137, you can’t simultaneously set e, h̄, and c all equal to on ...

Some Notes on SI vs. cgs Units
... The cgs unit for electric charge is the electrostatic unit, or esu. The size of the esu is set so that qq Coulomb’s Law is F = 1 2 2 . Notice that in the cgs system, Coulomb’s constant equals one. Therefore, r two charges each with charge 1 esu sitting 1 cm apart will feel a force between them of 1 ...

From all theory we know that the unit charge is equal to volume flow matter per time unit: Hence: (5) N.e0=V/t0 where t0 is equal to the spin time of an electrone and V is equal to the amount of volume, re-circled during the time t0. By inserting the value of N as we have calculated above, we get th ...

List of unusual units of measurement
An unusual unit of measurement is a unit of measurement that does not form part of a coherent system of measurement; especially in that its exact quantity may not be well known or that it may be an inconvenient multiple or fraction of base units in such systems. This definition is deliberately not exact since it might seem to encompass units such as the week or the light-year which are quite ""usual"" in the sense they are often used; if they are used out of context, they may be ""unusual"", as demonstrated by the Furlong/Firkin/Fortnight (FFF) system of units.
