Bully Metric

Six base units are included in the Bully Metric system. Three variants of the apan are defined as space-time units. And three variants of the nat are defined as transformation units.
The time apan (symbol ta) is by definition exactly 30.55 picoseconds. The length apan (or light apan) (symbol la) is by definition the distance light travels in vacuum in 30.55 picoseconds. The gravitational mass apan (symbol ma) is by definition the mass an object would have if its standard gravitational parameter (μ = MG) were equal to the speed of light in vacuum cubed, multiplied by 30.55 picoseconds.
The thermal nat (symbol Tn), has an SI equivalent value of 1.380649×10−23 J/K. The action nat (symbol An) has an SI equivalent value of (1/2pi) × 6.62607015×10−34 J⋅s. The rapidity/rotation nat (symbol Rn), does not have an SI equivalent value.
Apan Variants
ta = 30.55 picoseconds (exact) la = c × 30.55 picoseconds (exact) = 9.1586595919 millimeters (exact) ma = (c3 / G) × 30.55 picoseconds (exact) ≈ 12.3330 ronnagrams (approximate)
Nat variants
Tn = 1.380649×10−23 J/K (exact) An = (1/2pi) × 6.62607015×10−34 J⋅s Rn = does not have an SI equivalent value.
The above definitions ensure normalization of the speed of light and Newton's gravitational constant when using Bully units:

The Bully system includes units of transformation which are defined by analogy with units of information. These include the nat (n), bit (b), trit(t), and dit or digit (d). For each type of transformation unit, one may convert from nats to bits, trits, or dits, by multiplication with the natural logarithm as shown below:
b = n × loge(2) t = n × loge(3) d = n × loge(10) where loge is the natural logarithm.
The above definitions ensure normalization of Boltzmann's constant and Planck's constant when using Bully units:
kB = 1.0 Tn (exact)
= 1.0 An (exact)
Planck units and the Bully Metric
The following (table 1) was taken from the Wikipedia Planck units article:
Name | Expression | Value (SI units) |
---|---|---|
\frac{Planck time}{time apan} | 5.391247(60)×10−44 s | |
Planck length | 1.616255(18)×10−35 m | |
Planck mass | 2.176434(24)×10-8 kg | |
Planck temperature | 1.416784(16)×1032 K |
Since c and G are normalized in the Bully system, this ensures that Bully units should have a simple relationship with Planck's units. As illustrated below, multiplying each SI value from Table 1 by 566.66, results in the corresponding Bully value multiplied by 10-30:
566.66 × tP = 566.66 × 5.391247(60)×10−44 s = 3055.004(34)×10−44 s = 30.55004(34)×10−30 ps = 1.00001(11)×10−30 ta
566.66 × lP = 566.66 × 1.616255(18)×10−35 m = 915.867(10)×10−35 m = 9.15867(10)×10−30 mm = 1.00001(11)×10−30 la
566.66 × mP = 566.66 × 2.176434(24)×10-8 kg = 1233.298(14)×10−8 kg = 12.33298(14)×10−30 rg = 1.00001(11)×10−30 ma
SI prefixes will have the same meaning and conventions when used with apan variants as they have when used with standard SI units (see table in subsequent section for a list of SI prefixes). The "quecto" (symbol "q") metric prefix means 10-30. The relationship between Bully units and Planck's units can be summarized as:
566.66 × tP = 1.00001(11) qta 566.66 × lP = 1.00001(11) qla 566.66 × mP = 1.00001(11) qma
Planck units are understood to represent the smallest meaningful size of each quantity. For example, the Planck length is the smallest possible length because looking at small objects requires energy. If one were to build a microscope powerful enough to see objects of Planck length or smaller, the microscope would use so much energy that a black hole would form. In terms of Bully units, the "quecto" of each unit is 566.66 times larger than the absolute minimum size for that unit.
The Planck mass may seem unexpectedly large for a minimum mass value, but keep in mind that in this case the unit is for gravitational mass. There obviously are well defined and detectable masses that are smaller than the Planck mass (for example the electron and proton masses), but the Planck mass represents the boundary between gravitational mass and quantum mass. If an object has a mass larger than the Planck mass then gravitational effects will dominate. If the mass is smaller than the Planck mass then quantum mechanical effects will dominate.

The 'Bully Metric is an extremely efficient set of time and distance measurement units for representing earth's physical parameters. Bully units can efficiently represent the Earth's sidereal year and tropical year to eight digits; The Bully Metric can also efficiently represent four digit approximations for the Earth's radius (r ≈ 6371), Schwarzschild radius (R), standard gravitational parameter (μ = MG ≈ 3.984e14), and a typical gravitational acceleration on earth's surface (g ≈ 9.813 ).

Definition of the apan
The above approximations for earth's physical parameters can be further simplified by introducing new measurement units. The apan will be defined with two variants. The time apan (symbol ta) is by definition exactly 30.55 picoseconds. The length apan (or light apan) (symbol la) is by definition the distance light travels in vacuum in exactly 30.55 picoseconds.
SI prefixes will have the same meaning and conventions when used with the apan as the have when used with standard SI units (see table in subsequent section). For example:
One million ta = 1,000,000 ta = 1 mega time apan = 1 Mta = 30.55 μs One million la = 1,000,000 la = 1 mega light apan = 1 Mla = 9.1586595919 km
