tbh just went to tescos and for 3 quid in the cooking utensil section they sell metal size cups all joined togeter so you get 1/4 1/3 /1/2 and 1 cup for the cash
It very difficult to convert cups to metic as cups measure volume and we weigh in weight; half a cup of sugar is not the same weight as half a cup of flour.
Our local poundland do the measuring cups and spoons all together and I find them really simple to use. Faffed about measuring weights before I got them then got fed up.
Got my cups today in a big Tesco £3.50. So excited, just need something to fill them with now. Food wise that is before you lot start!! Don't you dare move from that bench
