Quoted from Completist:I didn’t think it was a stoopid question. The only dumb question is the one you never ask when you don’t know the answer lol.
Funny i was just replacing some disc caps on some playfield switches in my seawitch tonight. Check this out for scale - these are both the same value:

Just a quick comment since I deal with this daily in my designs: They might have a different voltage rating, or the dielectric (the 'stuff' between the plates) has different properties. Could be ceramic, porcelain, X7R, Y5V, etc. Usually you trade one property off for another (i.e for size vs. performance, etc.).
Here's a link for some quick info: https://www.electronics-notes.com/articles/electronic_components/capacitors/ceramic-dielectric-types-c0g-x7r-z5u-y5v.php
Don't mean to sound like a 'know it all', just more of a FYI.
