Convert millilitres to quarts

Content last reviewed:2026-09-30

A thousand millilitres is 1.0567 US liquid quarts, 0.8799 imperial quarts and 0.9081 dry quarts. Type a number of millilitres and the result appears straight away. The Quart type switch under the fields picks the measure. A carton marked 946 ml gives 0.9996 quarts.

US liquid: 0.946 l, the measure on American motor oil, milk and recipes. UK: 1.137 l, in British recipes and in Canadian weights-and-measures law. US dry: 1.101 l, for berries sold by volume.

How many quarts are in 500 ml?

Five hundred millilitres is 0.5283 US liquid quarts. A quart holds 946.35 millilitres[1], and the formula reads: quarts = millilitres ÷ 946.352946.

The same sum runs through the sizes that stand on a shelf. A 750-millilitre wine bottle gives 0.7925 quarts. A one-litre carton is 1.0567 quarts. A 1.5-litre bottle gives 1.5850 quarts.

The measure you choose changes the answer. Against an imperial quart, 500 millilitres gives 0.4399 quarts, and against a dry quart 0.4540 quarts. You pick the measure with the Quart type switch under the fields.

An American quart carton is labelled 946 millilitres, which works out at 0.9996 quarts. The label rounds a full quart of 946.352946 millilitres to a whole millilitre.

The other direction is in the quarts to ml converter, and a value in litres goes through the liters to quarts converter.

What is a quart, and what is a millilitre?

A quart is a quarter of a gallon in both the US and the imperial system, and the US dry quart is a separate measure. A US liquid quart holds 946.35 millilitres, an imperial quart 1,136.52 millilitres and a US dry quart 1,101.22 millilitres[1]. The name is shared by all three, which is why the Quart type switch sits under the fields.

A millilitre describes the same physical quantity in the metric system and equals a thousandth of a litre. It appears on a European label as ml, while technical documentation writes the same measurement as cm³, because both units describe one volume.

How do you convert millilitres to quarts? Formula and example

The whole calculation is one division. Take the number of millilitres, divide it by 946.352946, and the answer comes out in US liquid quarts.

Take a one-litre carton of stock. A thousand divided by 946.352946 gives 1.0567 quarts. One quart of stock is 946.35 millilitres, so the carton covers it and leaves 53.65 millilitres in the pack.

An imperial quart uses the divisor 1,136.5225 and a US dry quart 1,101.220942715. The Quart type switch substitutes the right number itself and recalculates the result when you change the measure after typing a value.

The related conversion runs through the ml to cups converter, because a cup is a quarter of a quart.

How many quarts is a given number of millilitres?

The rows cover label sizes and in-between values, from a hundred millilitres up to five litres. The columns match the options on the Quart type switch, and the answer carries four decimal places, the same as the result field in the converter.

How many quarts does a can or carton hold?

The sizes in this table are worked out from fluid ounces and quarts. That is why 473 millilitres gives 0.4998 quarts, almost exactly a half, and 946 millilitres almost a whole quart.

Pack size	US liquid quarts	What the pack is
341 ml	0.3603 qt	The Canadian steel drinks can of the 1970s and early 1980s, holding 12 imperial fluid ounces
355 ml	0.3751 qt	The Canadian drinks can in today's size, holding 12 US fluid ounces
473 ml	0.4998 qt	The American 16-fluid-ounce can, known as a tallboy
532 ml	0.5622 qt	The American 18-fluid-ounce can
568 ml	0.6002 qt	A can the size of an imperial pint, holding 20 imperial fluid ounces
946 ml	0.9996 qt	A US liquid quart rounded to a whole millilitre on the label
1,893 ml	2.0003 qt	Half a US gallon, which is two quarts

The can sizes come from the Drink can entry[2]. The Canadian steel can held 341 millilitres in the 1970s and early 1980s, and the 355-millilitre size took over there in the 1980s and 1990s with the move from steel to aluminium. The same sizes in pints come from the ml to pints converter, where 473 millilitres give 0.9996 of a US pint and 568 millilitres 0.9995 of an imperial pint.

How many quarts does a litre make in each of the three systems?

The rows match the options on the Quart type switch. The last column gives each quart's distance from a round litre, because that gap decides whether a one-litre carton covers a recipe written in quarts.

Quart type	Millilitres	Quarts in 1,000 millilitres	Distance from a litre	Option on the switch
US liquid	946.352946 ml	1.0567 qt	53.65 ml below a litre	US liquid
Imperial (UK)	1,136.5225 ml	0.8799 qt	136.52 ml above a litre	UK / Imperial
US dry	1,101.220942715 ml	0.9081 qt	101.22 ml above a litre	US dry

The NIST tables give a US liquid quart as 9.463 529 × 10⁻⁴ cubic metres and a dry quart as 1.101 221 × 10⁻³[1]. The full values in the first column follow from the American table of measures, which gives the liquid quart as 57.75 cubic inches, the dry quart as 67.200 625 and the inch as exactly 2.54 centimetres[3].

Which number formats does this converter handle?

The field accepts each of these formats and converts it, so you don’t need to tidy a number before you paste it. The table shows what the converter does with each one, and the converter worked out the results itself.

What you type	What the converter shows	How we read it
946.35	1 US qt	The point is the decimal separator, so this is 946.35 millilitres, which is one US quart.
946,35	1 US qt	A comma followed by two digits is read as a European decimal comma, so the result is the same.
1,500	1.585 US qt	Three digits after the comma mark a thousands separator, so we count one thousand five hundred millilitres. A note under the field says: Read as 1500. If you meant 1.5, type 1.5.
1 500	1.585 US qt	A space between the thousands is skipped, so this is one thousand five hundred millilitres, or one and a half litres.
1 l	1.0567 US qt	The field turns litres written with the l symbol into millilitres itself, so you can type a litre without any maths.
33 cl	0.3487 US qt	The field first turns centilitres written with cl into millilitres, as on a 33 cl can.
500 ml	0.5283 US qt	A unit pasted along with the number doesn’t get in the way, so we count five hundred millilitres.
32 fl oz	1 US qt	The field recognises fluid ounces from a US label by the fl oz symbol and converts them straight away: thirty-two ounces make one quart.

How do you read a quart off a label printed in millilitres?

The steps run from the figure printed on the pack to the value you put into an American recipe.

Copy the figure from the pack
A European or Canadian label gives the contents in millilitres or in litres. Multiply a figure in litres by a thousand, so 1.5 litres goes in as 1500.
Pick the quart type
For an American recipe and an American pack, choose the US liquid option. A British recipe from before metrication describes an imperial quart, which is the UK / Imperial option.
Read the number of quarts
The result appears as you type, to four decimal places. A hundredth of a quart is 9.46 millilitres, so for cooking the first two decimal places are enough.
Carry the number onward
The Copy result button puts the value on the clipboard. The Swap order button turns the converter round to quarts into millilitres, and the Clear all button empties both fields.

Why does an American pack say 946 ml?

An American carton of milk or stock has 1 QUART on the front and the figure 946 ml beside it. Both describe the same contents.

The reason sits in the rules for consumer packaging. The Fair Packaging and Labeling Act was amended in 1992 and has since required the quantity to appear in SI units as well, so that shoppers grow familiar with metric measures[4].

For a reader outside the United States that is convenient, because the millilitre figure is printed on the pack itself.

Three small American milk cartons on a white background, the front one reading Half Pint (236 mL) — The carton states the contents twice: as Half Pint and as 236 mL. That pair of figures is what the American packaging rules ask for, and 236 millilitres is 0.2494 quarts. Photo: Shannon VanDenHeuvel, Unsplash.
