"Right . . . what's a cubit?" That's an original line from one of Bill Cosby's early recordings about God telling Noah to build the ark. For anyone wanting to reveal their age, anyone else remember that? :-)
BTW, you're not building an ark, are you?
You can go to

cubit conversion is close to the bottom of the page.
This site doesn't have an exact conversion and I'm not sure anyone knows what the exact conversion is.
Maybe Sergy, Alex, Ken or someone else knows.
