Metric system and Imperial system

It isn't that bad.

The only thing I hate is converting Celsius to our units.

Honestly, all I can do is convert your units to Celcius and that's about it. I can't calculate miles, yards, or feet. Same goes for pounds, gallons, and other units.

I wish we could but u know

Sry...

I’m American and we use the metric system in science class and I’m even trying to start using it.

Same.
