Measurement

Mise à l'échelle

Définition

Le processus consistant à multiplier ou diviser des mesures par un facteur constant pour convertir entre des tailles, des représentations ou des unités tout en préservant les relations relatives.

Explication

A 1:50,000 map means every 1 cm on the map represents 50,000 cm (500 m) on the ground. Doubling a recipe scales all ingredient quantities by a factor of 2. In engineering, stress scales with the square of linear dimension — a bridge twice as tall must carry four times the wind load per unit area, which is why small models don’t predict full-scale structural behavior without scaling corrections.
