A metre is a metre everywhere because someone standardized it. Egypt did that first, with the royal cubit — fixed and state-enforced by the New Kingdom, around 1300 BCE.
The cubit began as the length from elbow to fingertip, but Egypt fixed it by decree to an exact standard length, about 52.3 cm. Working measuring rods were calibrated against it.
That is why the Great Pyramid’s four sides match to a hand’s width. Consistent measure made monumental engineering possible.
The world’s first standardized ruler was an Egyptian forearm, made official.
