Compression fittings; Oring vs Ferrule Size ?

[Squeeky]

In the process on finishing up plumbing for brewery. I'd like to switch all my compression ferrules over to orings. However do I just match up the ID or should I go smaller to its tighter. I realize you are supposed to use 2 orings instead of ferrule.

Are these sizes correct?

1/4 Compression for temp probe = 2x Size 010 orings 1/4 x 3/8 x 1/16
1/2 Compression (HERMS/Pickup) = 2x Size 014 orings 1/2 x 5/8 x 1/16

Just wanted to confirm prior to placing an order.
