Description
Numerical equivalence (symbol ≡) indicates that two quantities are numerically equal, even if the full meaning may be different. For instance: 1 ≡ 1·1 and 1 ≡ 1/1. In contrast to ≡, the symbol = indicates physicochemical equality.
Abbreviation: ≡

Example
- Iconic symbols indicate equality beyond equivalence, for instance in equations for the protonmotive force pmF (Blue Book Eq. 8.1 and 8.2)
- Conventional symbols:
The protonmotive force pmF Format Definition Units charge format: Δp ≡ ∆𝜇H+ ∙ (𝑧H+ ∙ 𝐹)−1 + ∆𝛹p+ [J∙C-1 = V] amount format: Δ𝜇̃ H+ ≡ ∆𝜇H+ + ∆𝛹p+ ∙ (𝑧H+ ∙ 𝐹) [J∙mol-1 = Jol]
- Iconic symbols: ΔmFH+ = ΔdFH+ + ΔelFp+
