几何化单位制 Geometrized unit system

(重定向自Geometrized units)

几何化单位制geometrized unit system),不是一种完全定义或唯一的单位制。在这单位制内,只规定光速与重力常数为1,即 c = G = 1 。这样留出足够空间来规定其它常数,像波兹曼常数或库仑定律:

 k_B = 1
 \frac{1}{4 \pi \epsilon_0} = 1

假若约化普朗克常数也规定为  \hbar = 1,则几何化单位制与普朗克单位制完全相同。

Geometrized unit system 几何化单位制

(重定向自Geometrized units)

A geometrized unit system or geometric unit system is a system of natural units in which the base physical units are chosen so that the speed of light in vacuum, c, and the gravitational constant, G, are set equal to unity.

The geometrized unit system is not a completely defined or unique system: latitude is left to also set other constants to unity. We may, for example, also set Coulomb's constant, ke, and the electric charge, e, to unity.
