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 2.997930×10E10 cm/sec
Mass gram 0.7425×10E-28 cm/g
Energy erg 0.826×10E-49 cm/erg
Electric charge e 1.381×10E-28 cm/e
Temperature ° Kelvin 1.140×10E-65 cm/°K
