What is a scale used for?
Weighing scales and balances measure weight by measuring the amount of force exerted on the load cell. They then convert that result to mass and display it in various units of mass. If they didn’t convert it to kilos or pounds, the result would be measured in Newtons. Scales give different results based on gravity.
What is a scale on a drawing?
