1407 - Why is it necessary to choose an appropriate scale when measuring?

It's necessary to choose an appropriate scale when measuring because it helps you get accurate and useful results. Imagine measuring a small book with a ruler that only has big marks (like meters or yards). You wouldn't be able to get an exact measurement.

If you choose a ruler with smaller marks (like centimeters or inches), you can get a more precise measurement. This is especially important in math, science, and other activities where small differences can make a big difference.
