UMS Units
Universal measurement is a system of units based on constants thought to be appropriate for use throughout the universe.
The fundamental standard of this system is the electron: the base units for mass, distance, and time are based on its classical physical properties. (Recent advances in particle physics regard the electron as a point charge without radius; nonetheless, the classical radius is still a well-defined constant quantity likely to be familiar to any advanced civilization.)
Distance
| Unit |
Abbrv |
Basis |
| tit |
(t) |
The classical radius of an electron at rest. (Also known as the tic, a name assigned by Mark Bollman® on a number of occasions when he has taught about this system to various mathematics and physics classes.) |
| tic |
(t) |
Alternate name for the tit. |
| tad |
(T) |
1015 tits(tics). |
Mass
| Unit |
Abbrv |
Basis |
| dash |
(d) |
The mass of an electron at rest. |
| holbrook |
(hbk) |
1030 dashes. |
Time
| Unit |
Abbrv |
Basis |
| flash |
(f) |
Time taken for light to travel the classical radius of an electron in a vacuum. |
| jiffy |
(J) |
1026 flashes. |
| bluemoon |
(bm) |
1030 flashes. |
| hellfreeze |
(hf) |
1035 flashes. |
Temperature
| Unit |
Abbrv |
Basis |
| scorch |
(s) |
10-1×Triple point of hydrogen (100% 1H isotopes) |
Electricity
| Unit |
Abbrv |
Basis |
| -1 zap |
(z) |
The charge on an electron. This quantity is chosen so that an electron has charge of -1 zap and a proton has charge +1 zap. |
Amount of Substance
| Unit |
Abbrv |
Basis |
| jimpop |
(jp) |
The number of elementary objects equal to the number of atoms in .1 hbk of hydrogen-1. |
Luminous Intensity
| Unit |
Abbrv |
Basis |
| gary |
(g) |
The luminous intensity generated from the photon emitted by an electron jumping from the first excited state to the ground state in a hydrogen atom. |
Supplemental unit: Volume
While the official unit of volume in this system is the cubic tit, universal measurement follows the example set by the metric system in choosing a slightly more convenient unit for commonplace measurements. The stonesink was added to the system in 1997.
