Cubic feet to quarts (ft³ to qt) converter

What is a cubic feet to quarts converter?

A cubic feet to quarts converter is an online tool that translates a volume expressed in cubic feet (ft³) into its equivalent in quarts (qt), and the other way around. Cubic feet describe a three-dimensional volume — the space occupied by a cube measuring one foot on each side — while the quart is a liquid capacity unit common in the United States. Because these units come from different measuring traditions, jumping between them by hand is awkward, and this converter removes the guesswork.

The tool is bidirectional: enter a value on either side and the matching figure appears instantly. It also supports gallons (gal), liters (L), and milliliters (mL), so you can mix and match the source and target units that suit your task.

How does the converter work?

The converter holds a fixed set of relationships between volume units. When you type a number into the cubic feet field, it first reads the unit you have selected, converts that quantity into a common internal reference, and then expresses the result in the unit chosen on the quarts side. Editing either field recalculates the other, so the two values always stay in sync.

The cornerstone of the conversion is that one cubic foot equals about 28.3168 liters, and one US quart equals about 0.946353 liters. Dividing the first by the second gives the key ratio used throughout this page.

Formula for conversion

To convert cubic feet to US quarts, multiply by the conversion factor:

$\text{qt} = \text{ft}^3 \times 29.9220$

To go the other way, from US quarts to cubic feet, divide by the same factor (or multiply by its reciprocal):

$\text{ft}^3 = \text{qt} \times 0.0334201$

Because the converter also handles liters, it is useful to remember the direct relationship between cubic feet and liters:

$\text{L} = \text{ft}^3 \times 28.3168$

Conversion table

The table below lists common cubic-foot volumes and their equivalents in US quarts, US gallons, and liters.

Examples

Example 1: One cubic foot to quarts

A single cubic foot of water needs to be expressed in quarts. Multiply by the conversion factor:

$1 \text{ ft}^3 \times 29.9220 = 29.922 \text{ qt}$

So one cubic foot is about 29.922 US quarts.

Example 2: Quarts back to cubic feet

Suppose you have 32 US quarts of liquid and want to know the volume in cubic feet:

$32 \text{ qt} \times 0.0334201 = 1.06945 \text{ ft}^3$

The 32 quarts occupy roughly 1.06945 cubic feet.

Example 3: Two cubic feet to quarts

Doubling the first example, two cubic feet convert as follows:

$2 \text{ ft}^3 \times 29.9220 = 59.8441 \text{ qt}$

Example 4: Cubic feet to liters

If instead you select liters on the right-hand side, one cubic foot converts directly:

$1 \text{ ft}^3 \times 28.3168 = 28.3168 \text{ L}$

Notes

• The quart values on this page are US liquid quarts; the UK (Imperial) quart is larger, at about 1.1365 liters, so be sure you know which standard your figures follow.
• Cubic feet measure pure geometric volume, which is why the converter pairs naturally with liquid units like quarts, gallons, and liters.
• Entering 0 returns 0, and clearing both fields leaves the converter blank — nothing is calculated until you supply a value.
• For large quantities, such as 100 cubic feet, the result scales linearly: 100 ft³ equals about 2992.205 US quarts.

Frequently asked questions

How many quarts are in a cubic foot?

One cubic foot contains about 29.922 US quarts. The figure comes from dividing the volume of a cubic foot (≈28.3168 liters) by the volume of a US quart (≈0.946353 liters).

How do I convert quarts back to cubic feet?

Multiply the number of US quarts by 0.0334201, or divide by 29.9220. For example, 32 quarts equal about 1.06945 cubic feet.

Are these US or UK quarts?

The converter uses US liquid quarts. If you need Imperial (UK) quarts, remember that they are roughly 20% larger, so the cubic-foot equivalent will differ.

Can I convert cubic feet to liters or gallons instead?

Yes. Each side of the converter lets you pick gallons, liters, or milliliters in addition to cubic feet and quarts. For instance, one cubic foot equals about 28.3168 liters or 7.481 US gallons.

What happens if I enter zero or leave the field empty?

Entering 0 produces a result of 0. If both fields are empty, nothing is calculated and the converter simply stays blank until you type a value.

Why might my result look slightly different elsewhere?

Small differences usually come from rounding or from mixing US and UK units. This converter uses the standard US liquid quart and rounds displayed results, so minor variations between tools are normal.
