The Exact Relationship Between Magnitudes

A disciplined mathematical ledger. Linear and affine relationships formulated with historical provenance and zero approximation compromise.

Mathematical Thesis

meter relative to kilometer

Under the international convention of physical quantities, conversion constitutes a linear scalar projection. The relationship is governed by the factor ratio between their definitions relative to the SI coherent base unit.

Analytical Formula
1 m = 0.001 km
1 km = 1000 m
