eli5: Why is there 1%, 2%, and whole milk but not any other percentage?

Question

I just feel like its weird how the percentage goes from 1-2% to whole.

Also, what do these percentages even mean? How can you turn milk into 1% or 2% milk?

Answer 1

0.5% was common in the US Midwest up until a couple years ago. Cream, half and half, and heavy whipping cream are also commonly available.
