Question

2 cups (into mL of water

Answer 1

about 473 mL

Explanation:

For liquid measure, there are 16 cups in a US gallon, which is exactly 231 cubic inches. Each cubic inch is exactly 2.54³ = 16.387064 cubic centimeters--the same number of mL.

So, the exact conversion from cups to mL is ...

1 cup = (231/16)(16.387064) mL = 236.5882365 mL

Multiplying this by 2 gives ...

2 cups = 473.176473 mL

For many purposes, the nearest mL is sufficiently accurate:

2 cups ≈ 473 mL
