At the following URL, 'geometric units' are discussed.

Here is an excerpt:

*****************************************************
A particularly convenient and elegant choice is the system of geometric
units, obtained by setting Newton's gravitational constant G, the speed
of light c, and Boltzmann's constant k all equal to 1. We can then
express any of the following units as a length in centimetres by
multiplying by the following conversion factors.

Quantity Unit cm Equivalent
Time second 2.99793010E10 cm/sec
Mass gram 0.742510E-28 cm/g
Energy erg 0.82610E-49 cm/erg
Electric charge e 1.38110E-28 cm/e
Temperature Kelvin 1.14010E-65 cm/K
