Quarts to fluid ounces volume units conversion factors are listed below. To find out how many ounces in quarts, multiply by the conversion factor or use the converter if converting between US fluid measurements. 1 Quart [US] = 32 Fluid Ounces [US], 1 Quart [UK] = 40 Fluid Ounces [UK]. There are 32 fluid ounces in a quart, because from the largest to the smallest units between quart and fl. oz, there are 2 pints in a quart, 2 cups in a pint and 8 fl. ounces in a cup, that makes 2 * 2 * 8 = 32 fl. ounces in a quart.
For example, to calculate how many fluid ounces there are in a half (1/2) quart of water or milk, multiply the quart value by the conversion factor, (1/2) * 32 = 16 fl. ounces of water or milk in a half quart. For US quarts, there are 4 oz in 1/8 US quart, 8 oz in a quarter (1/4) US quart, 10.6 oz in 1/3 US quart, 21.3 oz in 2/3 US quart and 24 oz in 3/4 US quart. For UK quarts, there are 5 oz in 1/8 UK quart, 10 oz in a quarter (1/4) UK quart, 13.3 oz in 1/3 UK quart, 26.6 oz in 2/3 UK quart and 30 oz in 3/4 UK quart. Quart is a volume measurement unit in US customary and imperial systems.
