Pint is half size of a quart, so the conversion factor from pints to quarts is 0.5 (it's the same for fluid and dry measurement between either from US pints to US quarts, or from UK pints to UK quarts). To find out how many quarts in pints, multiply by 0.5 or instead, use the converter.
1 Pint = 0.5 (1/2) Quarts [US, UK, fluid or dry]
For example, to find out how many quarts of water or milk there are in a US pint, multiply the pint value by the conversion factor, 10 * 0.5 = 5 quarts of water or milk.
For your information, 1 US pint of water weighs about 1 lbs or 16.7 ounces or 0.473 kilograms. 1 US pint of milk weighs about 1.07 pounds, or 17.2 ounces or 0.4875 kilograms (it can be a bit lighter or heavier based on the fat percentage).
UK pints are larger than the rest of them, so the heaviest. 1 UK pint of water weighs 1.25 lbs or 20 ounces or about 0.56 kilograms. 1 UK (imperial) pint of milk weighs about 1.2875 pounds, or 20.6 ounces or 0.585 kilograms (it can be a bit lighter or heavier based on the fat percentage).
Pint and quart are imperial and US customary volume units. There is one type of pint and quart in imperial system and 2 types (liquid and dry) in US customary system. The abbreviation for pint is "pt" and for quart is "qt".
