Although the relationships above are the exact same in both the united state customary and also imperial systems of measurement, both systems use different definitions of a gallon. As such, a quart is a 4 minutes 1 of a gallon in both systems, but the yes, really measurement of every quart is different. Lock are generally compared in regards to milliliters. Since 1 us gallon is same to 3,785.412 mL and 1 imperial gallon is same to 4,546.092 mL:

US customary system:

1 quart = 946.353 mL1 pint = 473.177 mL1 cup = 236.589 mL1 gill = 118.295 mL

Imperial system:

1 quart = 1136.523 mL1 pint = 568.262 mL1 cup = 284.131 mL1 gill = 142.065 mL

The US further differentiates quarts right into liquid quarts and also dry quarts:

US liquid quart = 946.353 mL

US dried quart = 1101.221 mL

Knowing (or referencing) the over relationships permits us come convert between various units of measurement. This is important because it enables people about the people to interact measurements even if various measurement systems room used.
