Which aspect do you find the most confusing? Is it the fact that after decimal point there are only two zeroes?

The test that I tried doing on myself is "without looking it up, can I buy a beer for 0.0001 BTC?" I already have some feel on sats that couple thousand sats is around a dollar, but the number above makes it quite hard to figure out how many sats is that.

If I use the format with padding, "0.00'010'000 BTC", then I'm able to guess that yea, that should be just about enough to get a beer at a bar. For smaller amounts like this it would be probably better to have just "10k sats", but then for amounts around $1000 I think this format can help.
