Dimensional Units for Coulomb in SI

Click For Summary
The discussion centers on the dimensional formula for the Coulomb in SI units, specifically seeking a representation that excludes amperes. Participants clarify that the Coulomb is defined as a derived unit (1 C = 1 A × 1 s) and cannot be expressed solely in terms of base units like meters, kilograms, and seconds. The consensus is that the Ampere, being a base unit, cannot be redefined in terms of other base units without contradicting the SI system's definitions. Attempts to derive a formula for the Coulomb using only m, kg, and s are deemed impossible, reinforcing the independence of these base units. Ultimately, the conversation highlights the limitations of dimensional analysis within the SI framework.

Yes, but the argument is more than two years old. PF discourages reviving old threads (a practice which is called necro-posting.)

You can, however, start your own thread, and refer to another thread, if you wish.

Coulomb has dimensions of [M]^1/2 * [L]^3/2 * [T]^-1
No, it doesn't. See the official BIPM page: http://www.bipm.org/en/measurement-units/base-units.html
