@Aaronut Thanks for the helpful other question link. –  abcd Jul 2 '14 at 10:08

A US cup is 237 mL.

It is more practical to use grams though:
256 grams of milk and 156 grams of oats.

WolframAlpha is the perfect place to look up these kind of things:

I just have have the ml measuring vessel, not the grams one, so what should I assume w.r.t ml for both of them? –  abcd Jun 14 '14 at 8:44
237 mL for both. –  soegaard Jun 14 '14 at 8:45
ok, thanks...... –  abcd Jun 14 '14 at 8:47
I seldom get in trouble using 250 ml as the conversion factor. It's wrong by a bit, but when a recipe calls for a cup of this and a cup of that, the ratio ends up correct. It's also easier to remember, and measure using metric cookware. –  Wayfaring Stranger Jun 14 '14 at 12:01
We Americans still haven't learned to cook by weight, for the most part. –  keshlam Jun 14 '14 at 15:34
