@iko I like to point out that in the battle between Imperial and metric, cups and spoons are neutral.
As a Canadian I've long ago dropped gallons, quarts, pints and ounces (fluid and weight - WTF was that?), but still embrace cups and spoons along with my grams and milliliters.
Cups and spoons are neutral, object-oriented and coexist nicely with the sanity of metric. One cup as 250ml is key info.
