There are 16.39 cc's in a cubic inch; one cc is 0.061 cubic inch (hence the .061 engines -- they're 1cc).

6.5cc is .397 cubic inch, or a 40; 6.6cc is 0.403 cubic inch -- or a 40, depending on who's selling.

(1 inch = 2.54 centimeters, by definition.  (2.54 cm)³ = 16.39 cc, or 16.387064 for the picky folks.  1/16.39 = .061).

Best advice I can give is to go to https://joshmadison.com/convert-for-windows/ and download his small program which gives an easy conversion for just about anything you'll ever need. Or not need because once I used it to convert the wingspan of a model from inches to light years :).

Or just commit the figure of 25.4mm per inch to memory, and go from there whenever you need to go from metric to Imperial.

And there's 28 grams per ounce, as every high school kid knows (well, at least the pot-heads do).

Do what Tim Westcott did:

The magic number is    .061

CI to CC =  CI divided by .061= CC

CC to CI =  CC times .061 = CI

.46 CI divided .061 = 7.509 CC
7.5 CC times .061 = .458 CI (or 46 if you will)
