How orbital period (and other formulas) become transparent, with all constants and SI baggage removed, leaving only the true natural ratios.
The Planck Unit Definitions (PUCS Framework)
Let’s recap the process:
1. Start with SI Gravity Constant
2. Remove SI “kg” and “m” via Scaling Factors
Mass-frequency ratio:
Naturalized G:
This gives in units of :
3. Isolate Planck Time
Planck time (non-reduced):
4. Define Other Planck Units via Planck Time
Planck length:
Planck mass:
Planck temperature:
These are not mysterious boundaries, but the unit harmonizers: the scales where our SI units match the universe’s natural ratios.
Orbital Period in PUCS Notation
1. Start with the Standard SI Formula
2. Express in Planck Units
Plug these into the formula:
3. Substitute Planck Unit Definitions
Recall:
Plug these in:
4. Simplify
Numerator:
Denominator:
So,
cancels.
Final Result (PUCS Notation)
= radius in Planck units =
= mass in Planck units =
= the Planck time scaling factor
= radius in Planck units =
= mass in Planck units =
= the Planck time scaling factor

Interpretation
All SI scaling is gone: Only the natural ratios and remain.
is the only “unit” left: It simply converts from Planck time to seconds.
No “mystery” or “breakdown” at the Planck scale: It’s just the scale where our units harmonize.
is the dimensionless mass in Planck units (not the scaling factor).
is the Planck mass scaling factor (in kg).

| Planck time | s | |
| Planck length | m | |
| Planck mass | kg | |
| Planck temperature | K |
Conclusion
This method makes the unit harmonization process explicit and operational:
Planck units are not physical boundaries, but the scales where SI units are rescaled to match nature’s ratios between equivalences.
The orbital period formula (and all physics) becomes a simple, dimensionless relationship, with only a single scaling factor () remaining to convert to SI seconds.
This is the true, practical meaning of “working at the Planck scale”-it’s not a breakdown, but a harmonization.
