US quarts to US cups
One US quart is 4 US cups.
1 US quart = 4 US cups · 1 US cup = 0.25 US quarts
This factor is exact, not rounded. It comes from the definition of the units rather than from a measurement, so the only limit on precision is how many digits are worth showing.

How the conversion works
Multiply by 4 to go from US quarts to US cups, or by 0.25 to go back the other way. Both figures are exact rather than rounded: they follow from the definitions of the units, not from anybody measuring something.
Four cups to a quart, and the name says so if you know where to look: a quart is a quarter of a gallon.
