Scales are broken... how can I measure stuff?

My scales are broken and I'm not going to have chance to buy any more for a few days. Is there any way I can measure stuff reasonably accurately temporarily? There are some things like a 30g portion of cheese or a sweet potato that I've measured enough to estimate it by sight now, but stuff like porridge oats or yoghurt or meat I have no idea.

I definitely don't want to rely on spoonfuls, because I'm 90% certain that my 'teaspoonful' is at least twice as generous as it should be. I don't really trust myself to just guess things by sight because then I'll log them inaccurately. It'll be at least a week before I have chance to buy new scales because I'm right in the middle of exams at the moment so I don't have time to go shopping for cheap new ones.

Any suggestions?
