I’m confused, how is pi used as a unit? My understanding is that it’s a number

Who said Pi is infinite? If we take Pi as base unit, it is exactly 1. No fraction, perfectly round.
Now everything else requires an infinite precision.

6π is an acceptable answer for finding the circumference of a circle with a radius of 3 units of something.

1 is also a number, a number we chose by convention to be a base unit for all numbers. You can break down every number down to this unit.
20 is 20 1s. 1.5 is 1 and a half 1.
If we have Pi as a unit, circumference of a circle would be radius*2 of Pi units. But everything that doesn’t involve Pi would be a fraction of Pi, e.g. a normal 1 is roughly 1/3 of Pi units, 314 is roughly 100 Pi units, etc. etc.

Eek, that makes my skin crawl. Taking what you said literally would imply that π² = π.

I’m pretty sure a base-Pi counting system would mean that Pi is π, not 1.
You’d count π, 2π, 3π, 4π, and so on. It doesn’t change reality, just the way you count and represent numbers.
I might be off, but it’s definitely not π = 1.

You still think in 1-based system, Pi unit * Pi unit is Pi of Pi units or 3.14159… Pi units. Also, Pi unit / Pi unit is 1/Pi Pi units or 0.318309886183790… Pi units.
*Numbers written with digits are 1-based numbers.
