What is a US customary cup?

A US customary cup is a volume unit equal to exactly 236.5882365 milliliters, commonly used in cooking to measure liquid and dry ingredients.

What does an acre-inch represent?

An acre-inch is the volume covering one acre of area to a depth of one inch, used for measuring water volumes in irrigation and reservoir planning.

Why is the conversion result so small?

Because a cup (US) is much smaller than an acre-inch, the converted value will be a very small number requiring careful attention to scale.
