## 1 Answer

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? – Aquarius_Girl Jun 14 '14 at 8:44
• 237 mL for both. – soegaard Jun 14 '14 at 8:45
• 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
