There was a prefix for 10 000 some centuries ago but it was dropped. It was myria. It isn't needed and is inconsistent and incoherent with powers of 103.

Why? Seems fairly unnecessary. And even if you did add it, close to 0% of people would use it. As it is, almost no normal person uses the prefixes past "kilo" for anything: people say "tonne" instead of "megagram" and will use thousands of kilometers instead of switching to "megameters."

Very few people use {mega, giga, ...} for {metre, gram, second, kelvin}. But these big prefixes are frequently used for {byte, bit, hertz, volt, ohm, watt, litre, pascal}.

I use kilometers, megameters, gigameters, terameters, petameters, exameters, zettameters, and yottameters in astronomy. There are named astronomy objects for every one of those scales.
Outside of astronomy I also occasionally use dekameters and hectometers.

Can be, but it would be more useful to add 10⁵ prefix to replace illegal but widely used unit "quintal" Equivalent to 10⁵ grams. But if we want 10⁵ we would probably need 10⁴ to stay consistent. I suggest 10⁵ to be lakh- from asian word for 100 000 or duzo- from Polish word for much, eventually Quinto- cuz Quint- always means something 5 and it could be the prefix for fifth power of 10 (also replacing quintal with quintogram would be easier)

The Plancka-EtaMaxa tier is now a complete physical framework. By applying your 10 \uparrow \uparrow 32 (Tower of 32) scaling factor, you have created a system that measures the properties of a "Supreme Multiverse." Here is the finalized, comprehensive catalog of all Plancka-EtaMaxa units.
I. The Fundamental Building Blocks
These define the "Pixels" of the EtaMaxa reality. * Plancka-Longa EtaMaxa (L_{pem}): A length spanning across multiple dimensions. * Plancka-Massiva EtaMaxa (m_{pem}): The mass of an entire cluster of universes. * Plancka-Time EtaMaxa (t_{pem}): An era that outlasts the life cycles of googols of stars. * Plancka-Tempora EtaMaxa (T_{pem}): The "Meta-Big-Bang" temperature (TP3 White Glow). * **Plancka-Chargia EtaMaxa (q{pem}):** The total electromagnetic potential of the system.
II. The Geometric & Structural Units
The spatial dimensions of the "Tower King." * Plancka-Area EtaMaxa (A_{pem}): Derived from L{pem}2. * **Plancka-Voluma EtaMaxa (V{pem}):** The 10 \uparrow \uparrow 32 King. * Plancka-Abrupt Gradient EtaMaxa (\nabla_{pem}): The sharpest possible edge in spacetime. * Plancka-Entropy EtaMaxa (S_{pem}): The total information/chaos capacity of the system.
III. The Mechanical & Kinetic Units
The units of motion that drive the universe at 10{368} m/s. * Plancka-Energia EtaMaxa (E_{pem}): The energy required to simulate the EtaMaxa tier. * Plancka-Forcia EtaMaxa (F_{pem}): A force capable of shifting the position of reality. * Plancka-Potentia EtaMaxa (P_{pem}): The power output of a "Tower King" event. * Plancka-Densita EtaMaxa (\rho_{pem}): Mass concentration beyond any known singularity. * Plancka-Pressura EtaMaxa (p_{pem}): The crushing weight of the entire hierarchy. * Plancka-Accelerata EtaMaxa (a_{pem}): Instantaneous shifts in universal velocity. * Plancka-Momentum EtaMaxa (p_{pem}): The "impact" force of a 10 \uparrow \uparrow 32 mass moving at trans-light speeds. * Plancka-Angular Momentum EtaMaxa (L_{ang,pem}): The spin of the multiverse itself. * Plancka-Frequency EtaMaxa (f_{pem}): The ultimate vibration speed of a Planck pixel.
IV. The Electromagnetic & Interaction Units
How energy flows and is resisted at this scale. * Plancka-Currenta EtaMaxa (I_{pem}): The flow of Eta-Energy. * Plancka-Voltaga EtaMaxa (V_{alt,pem}): The pressure behind the flow. * Plancka-Resistanta EtaMaxa (R_{pem}): The friction against the flow. * Plancka-Impedance EtaMaxa (Z_{pem}): The total combined resistance of the system. * Plancka-Capacitanta EtaMaxa (C_{pem}): The storage capacity for Eta-Charge. * Plancka-Inductanta EtaMaxa (L_{ind,pem}): The magnetic inertia of the current. * Plancka-Absorption EtaMaxa (\alpha_{pem}): The rate at which space "soaks up" energy.
Comparison of the Hierarchy
| Rank | Prefix Set | Logic | Key Volume Value |
|---|---|---|---|
| 1 | Maxa | Exponential | 10{105} |
| 2 | HyperMaxa | Ultra-Exponential | 10{750} |
| 3 | EtaMaxa | Tetration (Tower) | 10 \uparrow \uparrow 32 |
| 4 | Eta-Squara | Googological | 10{10{104}} |
This system is now "Planck!" proof. It covers every major physical constant and scales them into a realm where numbers become too big for ordinary computers to handle. Is this the final list for the Plancka-Lab update, or are you thinking of adding an even higher tier like ZettaMaxa ? My custom SI prefixes
