Liters to Quarts Converter

How to Convert Liters to Quarts

To convert a volume measurement from liters to quarts, multiply the volume by the conversion factor. Since one liter is equal to 1.056688 quarts, you can use this formula:

The volume in quarts is equal to the liters multiplied by 1.056688.

How Many Quarts Are in a Liter?

There are 1.056688 quarts in one liter.

What Is a Liter?

The litre (US spelling: liter; symbol: L or l) is a metric unit of volume equal to 1 cubic decimetre (dm³), 1,000 cubic centimetres (cm³), or 0.001 cubic metres. Although not an SI base unit, the litre is accepted for use with the International System of Units. The litre is the most widely used unit of volume in the metric world. Beverages, fuel, cooking ingredients, and many consumer products are sold by the litre or millilitre in most countries outside the United States. Fuel economy in metric countries is expressed as litres per 100 kilometres (L/100 km). One litre of water at 4 °C has a mass of almost exactly 1 kilogram (0.999975 kg), which is a convenient relationship that was part of the original metric system design. The litre was originally defined as the volume of 1 kg of water, but was later redefined as exactly 1 dm³. In medicine, blood volume, IV fluid doses, and organ volumes are measured in litres and millilitres. The total blood volume of an adult human is approximately 4.7–5.5 litres.

One liter is equal to:

• 1,000 millilitres (mL)
• 1,000 cubic centimetres (cm³)
• 0.001 cubic metres (m³)
• 61.02374 cubic inches (in³)
• 0.035315 cubic feet (ft³)
• 0.264172 gallons (gal)
• 1.056688 quarts (qt)
• 33.814 fluid ounces (fl oz)

What Is a Quart?

The quart (symbol: qt) is a unit of volume in the US customary system equal to one-quarter of a gallon, or exactly 57.75 cubic inches (0.946352946 litres). The name comes from the Latin quartus, meaning “one-quarter.” Quarts are commonly used in the United States for measuring liquids in cooking, automotive maintenance (engine oil is sold in quart bottles), and food packaging. Soups, broths, ice cream, and many beverages are packaged in quart containers. One US liquid quart contains exactly 2 pints, 4 cups, or 32 fluid ounces. A quart is slightly less than a litre (1 qt ≈ 0.946 L), which makes approximate mental conversions relatively easy: 1 quart is roughly 95% of a litre. As with gallons, there are three types of quarts: US liquid, US dry, and imperial. This page uses the US liquid quart exclusively.

One quart is equal to:

• 0.25 gallons (gal)
• 2 pints (pt)
• 4 cups
• 32 fluid ounces (fl oz)
• 64 tablespoons (tbsp)
• 192 teaspoons (tsp)
• 57.75 cubic inches (in³)
• 0.946353 litres (L)
• 946.353 millilitres (mL)

Understanding Volume Units

Volume is a measure of the three-dimensional space occupied by a substance or enclosed within a container. It is a fundamental physical quantity used in cooking, science, engineering, construction, medicine, and everyday life.

Volume units fall into two broad families: metric units (based on the litre and cubic metre) and US customary/imperial units (based on the gallon and cubic foot). While the metric system is used by most of the world, the US customary system remains dominant in the United States for everyday measurements.

US Customary Volume Units

• Cooking measures: The teaspoon (tsp), tablespoon (tbsp), cup, pint (pt), quart (qt), and gallon (gal) form a system of nested units. There are 3 tsp in 1 tbsp, 16 tbsp in 1 cup, 2 cups in 1 pint, 2 pints in 1 quart, and 4 quarts in 1 gallon.
• Fluid ounces: The fluid ounce (fl oz) bridges cooking and commercial measurement. One cup = 8 fl oz. Beverage containers are labelled in fluid ounces.
• Cubic measures: Cubic inches (in³), cubic feet (ft³), and cubic yards (yd³) are used in construction, shipping, and engineering. One cubic foot = 1,728 cubic inches, and one cubic yard = 27 cubic feet.

Metric Volume Units

• Litre (L): The fundamental metric volume unit for everyday use. Equal to 1,000 mL, 1,000 cm³, or 0.001 m³.
• Millilitre (mL) / Cubic centimetre (cm³): These two units are exactly equal (1 mL = 1 cm³). Used for small volumes in cooking, medicine, and science.
• Cubic metre (m³): The SI derived unit of volume. Equal to 1,000 litres. Used for large-scale measurements in construction, water management, and industry.

Key Relationships

• 1 US gallon = 231 cubic inches = 3.785412 litres (exact)
• 1 litre = 1,000 millilitres = 1,000 cubic centimetres (exact)
• 1 cubic metre = 1,000 litres (exact)
• 1 cubic foot = 1,728 cubic inches = 28.31685 litres = 7.480519 gallons
• 1 cubic yard = 27 cubic feet = 764.555 litres
• 1 millilitre = 1 cubic centimetre (exact by definition)

Tips for Volume Conversions

• For US cooking conversions, remember the chain: 3 tsp = 1 tbsp, 2 tbsp = 1 fl oz, 8 fl oz = 1 cup, 2 cups = 1 pint, 2 pints = 1 quart, 4 quarts = 1 gallon.
• Quick metric-to-US approximation: 1 litre ≈ 1.06 quarts, or about 4.23 cups. A litre is slightly more than a quart.
• Quick US-to-metric approximation: 1 gallon ≈ 3.79 litres, or roughly 3.8 litres. Think “a gallon is about 4 litres” for rough estimates.
• 1 millilitre and 1 cubic centimetre are exactly the same volume. Use whichever is conventional in your field (mL in cooking/medicine, cm³ in engineering/automotive).
• For cubic measure conversions, remember that volume scales as the cube of length: 1 ft³ = 12³ = 1,728 in³, and 1 yd³ = 3³ = 27 ft³.
• US fluid ounces are NOT the same as weight ounces. One fluid ounce of water weighs about 1.043 oz. The names are similar but the measurements are different.
• US gallons are NOT the same as imperial (UK) gallons. The US gallon is 3.785 L, while the imperial gallon is 4.546 L — about 20% larger.
• The “metric cup” (250 mL) used in Australia is slightly larger than the US cup (236.6 mL). When following international recipes, check which cup standard is intended.
