Bully Metric

Development Area

The following traditional units are accepted for use within the Buly system.
1 Bully Fathom = 200 kilopan (200,000 apan)
1 Bully Cubit = 50 kilopan (50,000 apan)
1 Bully Span = 25 kilopan (25,000 apan)
1 Bully Gallon = 5,000 cubed kilopan
1 Bully Stone = 500 Rn yta

Six base units are included in the Bully Metric system. Two variants of the apan are defined as spacetime units. Three variants of the nat are defined as transformation units. And the symbol "e" is used to represent elementary charge (the charge of a single electron). Traditional units of measure may also be accepted for use in the Bully system, provided the traditional unit is defined as a simple integer multiple of Bully base units.

The time apan (or timepan) (symbol ta) is by definition exactly 30.55 femtoseconds. The length apan (or lightpan or lengthpan) (symbol la) is by definition the distance light travels in vacuum in 30.55 femtoseconds.

The Bully Metric length unit

The infonat (natural unit of entropy) (symbol En) is defined such that for an ideal gas in a given macrostate, the entropy of the gas divided by the natural logarithm of the number of real microstates would be equivalent to one infonat.

Body	mass
Sun	161227199.623(5)	Rn ta
Earth	484.2442275(10)	Rn ta
Moon	5.9587358(11)	Rn ta

The rapinat (natural unit of rapidity) (symbol Rn) is defined such that an object with a standard gravitational parameter equal to the speed of light in vacuum cubed multiplied by 30.55 femtoseconds, will have a gravitational mass of one rapinat timepan. The dwarf planet Pluto has a gravitational mass of roughly one rapinat timepan. Earth's moon has a gravitational mass of approximately six rapinat timepan. It would take roughly six Pluto sized objects smashed together to build something the size of the moon. A few example masses are shown in Table 1.

Electron	23717311.411	An / ta
Neutrino	< 5.57	An / ta
Graviton	< 3.6	An / Zta

The actionat (natural unit of action) (symbol An), and elementary charge (symbol e), are defined such that if a Josephson Junction were exposed to microwave radiation of frequency 2 / 30.55 picoseconds (≈ 65.4664484 gigahertz), then the junction would form equidistant Shapiro steps with separation of 2π actionats per kilo-time-apan electron. Also,the quantum Hall effect will have resistance steps of multiples of 2π actionats per electron squared. A few example rest energies are listed in Table2.

Planck units and the Bully Metric

Table 3 below was taken from the Wikipedia Planck units article:

Table 3: Modern values for Planck's original choice of quantities

Name	Expression	Value (SI units)
Planck time	$t_{\text{P}}={\sqrt {\frac {\hbar G}{c^{5}}}}$	5.391247(60)×10−44 s
Planck length	$l_{\text{P}}={\sqrt {\frac {\hbar G}{c^{3}}}}$	1.616255(18)×10−35 m
Planck mass	$m_{\text{P}}={\sqrt {\frac {\hbar c}{G}}}$	2.176434(24)×10-8 kg
Planck temperature	$T_{\text{P}}={\sqrt {\frac {\hbar c^{5}}{Gk_{\text{B}}^{2}}}}$	1.416784(16)×1032 K

Planck to Bully conversion constant

Since c, G, k_B, and ħ are all normalized in the Bully system, this ensures that Bully units have a simple relationship with Planck's units. In fact, multiplying each value from Table 3 by 0.566660, results in the corresponding Bully value multiplied by 10^-30:

0.566660 × tP = 1.00001(11) × 10-30 ta
0.566660 × lP = 1.00001(11) × 10-30 la
0.566660 × mP = 1.00001(11) × 10-30 Rn ta

Table 4 below uses algebraic substitution to illustrate that there is one unique multiplicative constant that converts between Planck and Bully values. When Planck energy is included in the table (see "Planck energy" row in Table 4), one finds that the Planck to Bully conversion factor for energy is the inverse of the mass, time, and length conversion factor.

Table 4: Planck's units relationship with Bully units

Name	Expression
Planck time	$t_{\text{P}}={\sqrt {\frac {\hbar G}{c^{5}}}}={\sqrt {\frac {An{\frac {la^{3}}{Rn\,ta^{3}}}}{\frac {la^{5}}{ta^{5}}}}}={\sqrt {\frac {An}{Rn\,la^{2}}}}\,ta$
Planck length	$l_{\text{P}}={\sqrt {\frac {\hbar G}{c^{3}}}}={\sqrt {\frac {An{\frac {la^{3}}{Rn\,ta^{3}}}}{\frac {la^{3}}{ta^{3}}}}}={\sqrt {\frac {An}{Rn\,la^{2}}}}\,la$
Planck mass	$m_{\text{P}}={\sqrt {\frac {\hbar c}{G}}}={\sqrt {\frac {An{\frac {la}{ta}}}{\frac {la^{3}}{Rn\,ta^{3}}}}}={\sqrt {\frac {An}{Rn\,la^{2}}}}\,Rn\,ta$
Planck energy	$m_{\text{P}}c^{2}={\sqrt {\frac {\hbar {c^{5}}}{G}}}={\sqrt {\frac {An{\frac {la^{5}}{ta^{5}}}}{\frac {la^{3}}{Rn\,ta^{3}}}}}={\sqrt {\frac {Rn\,la^{2}}{An}}}\,{\frac {An}{ta}}$
Planck temperature	$T_{\text{P}}\times k_{\text{B}}=m_{\text{P}}c^{2}={\sqrt {\frac {Rn\,la^{2}}{An}}}\,{\frac {An}{ta}}$
∴	${\frac {t_{\text{P}}}{ta}}={\frac {l_{\text{P}}}{la}}={\frac {m_{\text{P}}}{Rn\,ta}}={\frac {\frac {An}{ta}}{m_{\text{P}}c^{2}}}={\sqrt {\frac {An}{Rn\,la^{2}}}}$

The meaning of Planck units

The Planck length and time units are understood to represent the smallest meaningful size of each quantity. For example, the Planck length is the smallest meaningful length because looking at small objects through a microscope requires energy. If one were to build a microscope powerful enough to see objects at Planck length or smaller, the microscope would use so much energy that a black hole would form. In fact, the existence of objects on the Planck scale would cause a black hole.

The Planck mass of 2.176434(24)×10^-8 kg is not a minimum value. In the case of mass, the Planck value is a crossover point. The Planck mass represents the boundary between gravitation and quantum mechanics. If an object has a mass larger than the Planck mass then gravitational effects will become more important. If the mass is smaller than the Planck mass then quantum mechanical effects will be more important.

Visible universe and the Bully Metric

Since Planck units represent the smallest meaningful length and time values, it seems appropriate to also consider the largest meaningful length and time value, and situate these within the Bully system. The universe is currently understood to be 13.7 billion years old, which is 14.15 × 10³⁰ ta in Bully units. The radius of the visible universe is 46.508 billion light years, which is 48.04 × 10³⁰ la in Bully units.

The apan prefix table

SI prefixes have the same meaning and conventions when used with apan variants as they have when used with standard SI units. See Table 5 below for the list of SI prefixes used with apan variants. Also shown in the table are the smallest (Planck scale) and largest (Visible Universe) values for each unit.
