320 cups. In US measure: 1 quart = 4 cups And 1 cup = 0.25 quart.
There are 32 US fluid ounces (2 pints, or 4 cups) in 1 US quart (946.4 ml).
There are 40 Imperial fluid ounces (2 pints) in 1 Imperial quart (1,136 ml).
Note that there is no 'cup' in the Imperial system, it is best to use pints or half pints, and not 'cups'.
That is 2.5 quarts.
8 oz. = 1 cup 16 oz. = 0.5 (or half) quart (also equals 1 pint) 32 oz. = 1 quart 64 oz. = 2 quarts 80 oz. = 2.5 quarts (or 5 pints)
An ounce is a unit of mass. A quart is a unit of capacity. The two units are therefore incompatible. However, there are 8 FLUID ounces in a cup, and since there are 4 cups in a quart, that would be 9 cups in 2.25 quarts, or a total of 72 FLUID ounces in 2.25 quarts.
80 oz 1 quart = 32 oz 1 oz = 0.03 qt 1 Imp. qt = 40 oz
2.5 qt 1 quart = 32 oz 1 oz = 0.03 qt 1 Imp. qt = 40 oz
To convert 80 fl oz to quarts, divide by 32 (since 1 quart = 32 fl oz). 80 fl oz is equivalent to 2.5 quarts. To convert 80 fl oz to pints, divide by 16 (since 1 pint = 16 fl oz). 80 fl oz is equivalent to 5 pints.
That is 1.25 quarts
12.5 quarts.
9.6875 quarts.
1.6875 quarts.
That is 1.844 quarts.
80 ounces is about 2 liters, although the exact answer when I did the conversion is 2.366! :)
