About Quarts and Fluid ounces
Quarts (qt): Two pints, or one quarter of a gallon (the name comes from this — 'quart' from 'quarter'); the US quart is 946 mL, UK imperial quart 1,136 mL. Common uses: Milk and juice container sizes in the US, motor oil, and large cooking measurements (stocks, broths).
Fluid ounces (fl oz): 1/128 of a US gallon, or 29.5735 mL; the UK imperial fluid ounce is slightly different at 28.4131 mL, a remnant of pre-metric British measurement. Common uses: US beverage container sizes (a 12-oz soda can), US liquid recipe measurements, and UK pub measures for spirits (where a 'single' is 25 or 35 mL but historically tracked from imperial fl oz).
