How to change sketches from MM to imperial

How do I change my file from MM to inches? I’ve done it before but I don’t see it now
thanks for any help

Window>Model Info>Units

Menu Window > Model Info > Units > make changes as you like.
Save the model with menu File > Save as template … if you wish to re-use these settings instantly
next time.

Thank you That did it. I knew it was simple…just couldn’t find it…Appreciate it much
