Drill bit questions

[Cherokee]

Guys whats a No. 47 or No. 33 drill bit?
IM building my trigger from a kit and it says to use these two bits. I have no idea what size that is.
My drill bits are in inches and my drill bit sizing chart has metric and inch on it.
Any help?

Thanks

It's not only computer standards that are so screwed (pardon the pun) up... drill sizes are measured in letter, wire size, fractional, and metric. #47 is wire size equal to .0785" #33 is .1130

There's a nice printable pdf chart with everything on it HERE.
