Are units of angle really dimensionless?

Angles might seem magic, but they’re actually just measurements, like how many steps you take around a circle.

Imagine you're playing on a round merry-go-round. When it spins, you can count how many big steps it takes to go all the way around. That’s kind of what we do with angles! Instead of counting steps, we use numbers like 360 for a full circle, that's like saying the merry-go-round took 360 tiny steps to make one full spin.

Now here’s where things get fun: even though you're using numbers, angles don’t really have a unit in the same way height or weight do. It’s more like how many slices of pizza you eat, it's just a number telling you how much of the whole circle you've covered.

But wait! Sometimes we use degrees (like 90° for a quarter turn), and that feels like a unit. However, those degrees are actually just another way of counting how many steps around the circle, they're not really making angles have units; they’re helping us count more easily.

So even though it looks like angles have units, they’re secretly just numbers telling you how much of a circle something has moved, and that makes them dimensionless! Angles might seem magic, but they’re actually just measurements, like how many steps you take around a circle.
