About Quarts

A quart (qt) is a US customary volume unit equal to 2 pints or 4 cups - approximately 946.353 mL (just under one liter). Motor oil, paint, and large containers of juice or milk are commonly sold by the quart in the United States. The term 'quart' derives from the Latin 'quartus' (fourth), as it is one quarter of a gallon. The US liquid quart (946 mL) differs from the UK imperial quart (1136 mL). Engine coolant, transmission fluid, and many automotive products are measured and sold in quart containers in the US. Four quarts equal one US gallon.

About Liters

A liter (L) is the fundamental metric unit of volume, equal to one cubic decimeter (1 dm³ = 1,000 cm³ = 1,000 mL). Since its adoption as part of the metric system in 1793, the liter has become the world's most widely used volume measurement for liquids. Bottled water, soft drinks, wine, milk, and engine oil are all routinely sold by the liter globally. One liter of pure water at 4°C weighs almost exactly one kilogram - a convenient property that makes the liter central to everyday science, cooking, and industry worldwide. The liter is also written 'litre' in British English.
