What is a Quart and a Liter?
The US liquid quart (symbol qt US) is a unit of volume in the United States customary units system. It is equal to one-quarter of a US gallon, which is exactly 57.75 cubic inches or approximately 0.946 liters. It is commonly used for measuring medium quantities of liquids, such as milk, oil, and juices.
The liter (symbol L or l) is a metric unit of volume. It is defined as exactly one cubic decimeter (1 dm³), which is equivalent to 1,000 cubic centimeters (cm³) or 0.001 cubic meters (m³). The liter is commonly used for measuring liquids and sometimes granulated solids.
Note: The Quart is part of the imperial/US customary system, primarily used in the US, UK, and Canada for everyday measurements. The Liter belongs to the metric (SI) system.
History of the Quart and Liter
The quart, meaning 'quarter part' (of a gallon), shares its history with the gallon. The US liquid quart is derived from the English wine gallon (231 cubic inches), making it distinct from the Imperial quart used elsewhere, which is based on the larger Imperial gallon.
The liter was introduced in France in 1795 as one of the new 'republican measures' and was defined as one cubic decimeter. The original symbol was 'l', but the symbol 'L' was adopted by the General Conference on Weights and Measures (CGPM) in 1979 to avoid confusion with the number '1'. While not an official SI unit (the SI unit for volume is the cubic meter), it is accepted for use with the SI.

Frequently Asked Questions
Questions About Quart (qt)
How many pints are in a US quart?
There are exactly 2 US liquid pints in 1 US liquid quart.
How many cups are in a US quart?
There are exactly 4 US customary cups in 1 US liquid quart.
Is a US quart the same as an Imperial quart?
No. The US liquid quart (≈ 0.946 L) is smaller than the Imperial quart (≈ 1.136 L).
About Liter (L)
Is a liter exactly 1 kilogram of water?
Approximately, yes, but not exactly. The original definition of the kilogram was based on the mass of one liter of water at its maximum density (around 4°C). However, the definition of the kilogram has since been refined based on fundamental physical constants. So, 1 liter of water has a mass very close to 1 kg under specific conditions, but it's not the definition.
What is the difference between L and l as symbols for liter?
Both are accepted symbols for the liter. 'L' was officially sanctioned to reduce ambiguity with the numeral '1', especially in print, but 'l' is still commonly used, particularly in scientific contexts where the font makes it distinct.
How does a liter relate to a cubic meter?
1 cubic meter (m³) is equal to 1,000 liters (L). Conversely, 1 liter is equal to 0.001 cubic meters.
