ELI5, why is the scale for how good something is x/5?

Question

Why do we measure things out of five? Like, 5 star hotels or restaurants? Why is it five and not, say, 37?

In: 0

Answer 1

It’s not always. We have many different ranking systems. Movies are often rated out of 10. Gymnastics are rated with decimal point precision. YouTube rates things out of 2, like or dislike. You’re thinking of one rating system and thinking it’s the only one.

Why not 37 though? Because 37 isn’t good to divide by. What percentage of 37 is 22? Idk about 60. It’s hard to estimate if your scale is out of 37.
