What Is Double 1½ Cups?
How to measure 3 cups
- With standard cups & spoons: 3 cups
- Tablespoon method: count out 48 level tablespoons. A cup is 16 tablespoons, so awkward cup fractions often come out to a clean number of spoons.

- By weight (most accurate): see the gram table below for common ingredients.
Here's the math: 1½ cups is 24 tablespoons. Take double of that and you get 48 tablespoons, which is 3 cups. Scaling up is forgiving for most ingredients — but see the FAQ below for the ones that aren't.
