Constants

There may be other factors that intervene in the relation between these two constants.

Wilson's solution is similar to Hudson's in that they used the same constants.

It is generally assumed that fundamental constants such as c have the same value throughout spacetime, meaning that they do not depend on location and do not vary with time.

The International Bureau of Weights and Measures says the new kilogram standard, for example, it will be based on three basic quantum constants — the Planck constant, the speed of light, and the natural microwave radiation of the cesium atom.
