Cubic inches and Quarts
Everything you need to know about converting quarts to cubic inches.
Quarts and Cubic Inches in Context
A quart (qt) is a US customary volume unit defined as exactly 1/4 of a US gallon, or 57.75 cubic inches. It's the standard measure for motor oil, transmission fluid, coolant, and other automotive fluids.
A cubic inch (in³ or cu in) measures the volume of a cube with 1-inch sides. It's widely used in the automotive industry for engine displacement — a '350 cubic inch' engine has a total cylinder volume of 350 in³, which equals about 5.74 liters or 6.06 quarts.
Automotive and Engineering Uses
Engine displacement in American muscle cars has historically been specified in cubic inches: the Chevy 350 (5.7L), Ford 302 (4.9L), and Dodge 440 (7.2L) are all named for their displacement in cubic inches. Modern engines typically use liters, but cubic inches remain common in hot rod, racing, and classic car communities.
Packaging and product design also use cubic inches. Shipping box dimensions (length × width × height in inches) give cubic inch volume, while liquid contents are labeled in quarts. Knowing that 1 qt = 57.75 in³ bridges these two measurement systems.
Quarts to Cubic inches Formula
1 US quart = 57.75 cubic inches. This is an exact definition in the US customary system. 1 gallon = 231 cubic inches, and 1 quart = 1/4 gallon = 231 ÷ 4 = 57.75 cubic inches.

Quarts → Cubic inches
1 US quart = 57.75 cubic inches. This is an exact definition in the US customary system. 1 gallon = 231 cubic inches, and 1 quart = 1/4 gallon = 231 ÷ 4 = 57.75 cubic inches.
Cubic inches → Quarts
To convert cubic inches back to quarts, divide by 57.75. For example, 350 cubic inches ÷ 57.75 = 6.06 quarts. This is particularly useful when converting engine displacement to fluid capacity.

Frequently Asked Questions
How many cubic inches are in 1 quart?
There are exactly 57.75 cubic inches in 1 US quart. This comes from the definition: 1 gallon = 231 cubic inches, and 1 quart = 1/4 gallon = 57.75 in³.
How many quarts is a 350 cubic inch engine?
A 350 cubic inch engine has a displacement of 6.06 quarts (350 ÷ 57.75). This is the total swept volume of all cylinders — not the oil capacity, which is typically 4-5 quarts.
How many cubic inches in a gallon?
There are exactly 231 cubic inches in 1 US gallon. Since 1 gallon = 4 quarts, and each quart = 57.75 in³: 4 × 57.75 = 231 in³.
How do I convert cubic inches to quarts?
Divide cubic inches by 57.75. For example, 500 cubic inches ÷ 57.75 = 8.66 quarts.
Is 1 quart exactly 57.75 cubic inches?
Yes. This is an exact value in the US customary system. The US gallon is defined as exactly 231 cubic inches, and 1 quart is exactly 1/4 gallon = 57.75 cubic inches.
How many cubic inches is a pint?
A US pint (half a quart) is 28.875 cubic inches (57.75 ÷ 2). A US cup (quarter of a quart) is 14.4375 cubic inches.
How do I use this for packaging design?
Calculate the internal volume of your container in cubic inches (length × width × height), then divide by 57.75 to get the capacity in quarts. For example, a box with internal dimensions 6×5×4 inches = 120 in³ = 2.08 quarts capacity.
