When a recipe says a 'cup' how much does it mean?

[PercyPigPie]

Our cups are all different sizes! Is there a more standard measurement?

My cup measure is 250ml

I use my cup measurement 250ml/180 grams

Yes there is. You need something like this. Many American recipes use cup measures rather than g or oz.

It's an american measurement, see here for conversion.

Also American pints are different so beware!

Saying that - conversion of ml/grams not appropriate ...

Depends what it is 180grams of, yeah.

Measuring in volume rather than weight for solid things seems weird to me.

You can just use your measuring jug though, don't need to buy a special cup measure.

An American pint is 16 fluid oz, UK pint is 20.

Aha, thanks.

If you have a look on here for a similar recipe ie ingredients, there is box to tick for conversion to metric measurements. This may help.
