About Liter to US Quart Conversion

Converting liter to us quart comes up frequently in cooking, chemistry, medicine, and engineering. A recipe written in metric units may need to be adapted for a kitchen using us quart, or a laboratory protocol may specify volumes in liter that need to be measured with equipment calibrated in us quart.

In everyday use, knowing that 5 L = 5.283 qt and 10 L = 10.57 qt covers most common situations. For bulk calculations, 100 L = 105.7 qt is a useful anchor. The reverse conversion — us quart back to liter — uses the factor 0.9464, so 1 qt = 0.9464 L.

All conversions use the internationally recognized factor of exactly 1 L = 1.057 qt. Calculations are performed in IEEE 754 double-precision floating point, giving accuracy to at least 8 significant figures — more than sufficient for any practical application.

Quick Answer

Formula: US Quart = Liter × 1.0566881

Multiply any liter value by 1.0566881 to get us quart. One liter equals 1.0566881 qt.

Reverse: Liter = US Quart × 0.946353

Worked Examples

One US quart
0.946 L × 1.0566881 = 0.99962699 qt
0.946 liters = 1 US quart — nearly identical in size.
One liter
1 L × 1.0566881 = 1.0566881 qt
1 liter = 1.057 US quarts — just over a quart.
US gallon
3.785 L × 1.0566881 = 3.9995646 qt
3.785 liters = 4 US quarts = 1 US gallon.
US pint
0.473 L × 1.0566881 = 0.49981349 qt
0.473 liters = 0.5 quarts = 1 US pint.

Mental Math Tricks

× 1.057

Liters × 1.057 = US quarts. Almost 1:1 — very close in size.

1 L ≈ 1 qt

One liter and one US quart are nearly identical (within 6%).

4 qt = 1 gal

Four quarts = one US gallon = 3.785 L.

Frequently Asked Questions

About Liter and US Quart

Liter (L)

The liter was introduced by the French metric system in 1793, defined as the volume of one kilogram of pure water at 4°C. The word derives from the older French unit litron, from Medieval Latin litra. It was redefined in 1964 as exactly 1 cubic decimeter.

France adopted the liter as part of revolutionary metric standardization, spreading across Europe with Napoleonic expansion. Today it is the standard unit for liquids in most of the world, from soda bottles to fuel pumps.

Interesting fact: A liter of water at 4°C weighs almost exactly 1 kilogram, which is why the kilogram was originally defined through it.

US Quart (qt)

The US liquid quart is one-quarter of a US gallon, equal to 946.353 mL. The word 'quart' comes from Old French quarte (fourth part), dating to medieval England.

Quarts are standard in American cooking and food packaging: motor oil, paint, cream, and ice cream are commonly sold in quart containers.

Interesting fact: The US quart and the Imperial quart differ significantly — the Imperial quart is 1.136 liters versus 0.946 liters for the US quart.
