  2. Dimensionless scalar ratio without base units
  3. Arbitrary empirical units without dimensional consistency
  4. Gravitational units only
Answer
Standard SI derived units defined by international physical constants for Units and Measurements

The correct answer is Standard SI derived units defined by international physical constants for Units and Measurements — The dimensional formula confirms consistency across both sides of the field equations.

Step-by-step solution

  1. Dimensional analysis converts base SI quantities (M, L, T, A) into the derived unit for Units and Measurements.
  2. The dimensional formula confirms consistency across both sides of the field equations.
