US quart and Millilitre
A quart is a quarter of a gallon, which is where the name comes from. Like the pint and the gallon it carries the US-versus-imperial difference with it.
A millilitre is exactly one cubic centimetre, which is why medicine and laboratory work quote both and mean the same thing.

Convert qt to ml: common questions
How many millilitres are in a us quart?
Exactly 946.352946. One us quart is 946.352946 millilitres, and the box above will do it for any figure you type.
Is this conversion exact, or rounded?
The ratio is exact. It is not a rounded constant typed into a table: it is derived from the definitions of the two units, so it agrees with any other correct converter to as many digits as you care to compare.
Why does another converter show a slightly different number?
Almost always rounding rather than disagreement. Many converters cut the answer to two or four decimals, and some carry a factor that was rounded before the multiplication rather than after. The figures here are computed from the exact definitions and only rounded on the way to the screen.
Where these figures come from
