Baking Conversions

I use a mixture of both cups and grams on here so I've made a list that might be useful, if you happen to use one or the other. Cup sizes vary depending on location so I have tried to provide the most widely used measurements.

For more detailed conversions visit my favourite, trusty and always on point sources: Traditional Oven and JoyofBaking.
