To convert cubic yards to US quarts, multiply by 807.8961039. That factor is the whole relationship: both units measure volume, so the conversion is a proportion with no offset and no substance-specific constant.
Twenty-seven cubic feet — the unit concrete, topsoil and gravel are ordered in. A quarter of a US gallon, just under one litre.
US and imperial measures share names and do not share sizes. The imperial gallon is 4.546 L against the US 3.785 L, and the imperial pint is 568 mL against 473 mL. A recipe or fuel figure is 20% out if the wrong gallon is used, so check which side of the Atlantic the number came from. Two tables follow: rounded steps for quick lookup, and a set of real reference quantities converted into US quarts, which is usually more useful than the bare number.

What is a cubic yard?
Twenty-seven cubic feet — the unit concrete, topsoil and gravel are ordered in.
What is a US quart?
A quarter of a US gallon, just under one litre.
Why does my answer differ from another converter?
Almost always because the other tool rounded the factor before multiplying. This page keeps full double precision through the calculation and rounds only for display, and it prints the factor it used so you can see where any difference came from.
Is there a quick way to do yd³ to qt in my head?
