About US fluid ounce (us fl oz)

The US fluid ounce (fl oz) is a unit of volume equal to approximately 29.574 milliliters, one sixteenth of a US liquid pint. It is the primary small-volume unit on US food labels, beverage cans, and pharmaceutical liquid measurements. A standard US soda can is 12 fl oz; a coffee shop "tall" is 12 fl oz; a standard shot is 1.5 fl oz. The US fluid ounce is distinct from the imperial fluid ounce (28.413 mL) and should not be confused with the ounce as a unit of mass.

A US soda can is 12 fl oz (355 mL). A US shot glass holds 1.5 fl oz (44 mL). A US water bottle is commonly 16.9 fl oz (500 mL).

About Imperial quart (imp qt)

The imperial quart is a unit of volume equal to one quarter of an imperial gallon, approximately 1.136 liters. It is used in the UK and Commonwealth countries for liquid measurement, though everyday use has declined since metrication. An imperial quart is larger than both the US liquid quart (946 mL) and just slightly larger than one liter. Historically, motor oil was sold in imperial quart cans in the UK; today, liter bottles have replaced them.

Pre-metrication UK motor oil was sold in imperial quart cans. An imperial quart is just over two UK pints.
