Another FAQ (well, one of mine!) put to rest in my own kitchen
I'm frequently Googling what the dried weight vs. cooked weight is of chickpeas - predominately because I detest the flavour of tinned chickpeas (I find they have a vaguely fishy and, unsurprisingly 'tinny' taint to them, so I won't use them for things like hummus etc.), and also for other people with this affliction. I try to make quantities in recipes convenient(ish) for people to cook them, where I can - so where I use them as an ingredient, if appropriate, I'll go in increments of 240g (as that is the drained weight of a can of a 400g tin of chickpeas), or 120g, so that people haven't got bits and bobs lying around.
So anyway, I usually cook my chickpeas in bulk (due to soaking time), cool and freeze in a big re-sealable bag so I have a ready and convenient supply whenever I want them - as convenient as tinned chickpeas, but taste nicer, and are far cheaper to buy! This time, I decided to weigh them after cooking, so I never have to Google it and wonder whether it's right again...
