How many cubic feet are in a quart?

One US liquid quart equals approximately 0.033420 cubic feet (ft³). More precisely, 1 qt = 57.75 in³ ÷ 1728 in³/ft³ ≈ 0.03342013889 ft³.

How do I convert quarts to cubic feet by hand?

Multiply the number of quarts by 0.03342013889. For example, 10 qt × 0.03342013889 = 0.3342 ft³. Alternatively, divide by 29.9220779.

Does this converter use US liquid quarts or UK quarts?

It uses the US liquid quart (946.353 mL). The UK/imperial quart (1136.52 mL) is about 20% larger. If your quarts are UK imperial, the result will differ.

How many quarts are in a cubic foot?

One cubic foot holds approximately 29.9220779 US liquid quarts (≈ 29.92 qt/ft³). Use the Swap button to perform that direction of conversion.

Why is the cubic foot result such a small number?

A cubic foot is a large unit — 1728 cubic inches or about 7.48 US gallons. A single quart is only about 1/30 of a cubic foot, so the ft³ value is always much smaller than the qt value.
