Also, depending on the ingredient, it makes more sense to use cups as a measurement of volume, not mass, when converting to metric. E.g. liquids, yoghurt etc.

Another thing: although not strictly metric, but European recipes also use tablespoon and teaspoon as measurements for smaller volumes, so no need to convert this.

Just my two cents, other than that very nice work!!

Please, please try using weight whenever possible, aka for all amounts >= 2 grams.

1. People are bad at measuring volume. This has been tested. There is much more variance in amounts measured by volume than be weight. See "science and cooking" (ferran adria).

2. Using a scale means doing a lot fewer dishes! (measuring cups, spoons, etc.)

3. It's faster, try it!

Hmmm... What kind of cup? :-)

US "legal" cup (240ml)

US customary cup (246,6ml)

metric cup (250ml)

UK cup (170,5ml)

edit: fixed typo 150ml -> 250ml

[Chilko]

Not sure where that 150ml came from - our metric country (New Zealand) 1 cup is 250 ml.

Or UK Breakfast cup (227,3ml)

Thanks for the feedback. I've made a note.

so use cups and tablespoons but put in parenthesis the value in mL
