Convert cubic inches to quarts accurately for engine displacement, fluid capacity, and precision machining. Essential for automotive professionals and engineers with real-world examples.
1 cubic inch equals 0.017316059170453445 quart
Formula: qt = in³ × 0.0173160
The conversion between cubic inches and quarts is fundamental in automotive and industrial applications. With 1 cubic inch equaling approximately 0.017316 quarts (or 1 quart equaling 57.75 cubic inches), precision matters significantly. This conversion bridges two measurement systems commonly used in North America, where cubic inches measure engine displacement while quarts measure fluid volumes.
Accurate cubic inch to quart conversion is critical for engine specifications, fluid capacity calculations, and regulatory compliance. A 350 cubic inch engine equals approximately 5.74 quarts of displacement—miscalculating this affects performance ratings, fuel efficiency projections, and parts compatibility. In manufacturing, precision errors compound across production runs, potentially costing thousands in rework or recalls.
Engine displacement is traditionally measured in cubic inches in North America, while fluid capacities (oil, coolant, transmission fluid) are specified in quarts. Engineers must convert between these units when designing engine blocks, calculating compression ratios, and specifying fluid requirements. The conversion ensures compatibility between legacy engine specifications and modern fluid capacity standards.
Machinists and manufacturing engineers work with both cubic inches (for part dimensions and cavity volumes) and quarts (for fluid capacity in hydraulic systems, cooling jackets, and reservoirs). Precise conversion prevents costly errors in tool design, mold cavity calculations, and hydraulic system specifications where fluid volume directly affects performance and safety.

This cubic inch to quart converter uses high-precision conversion factors to ensure accurate results for professional and academic use.
Our calculator provides results with up to 10 decimal places for maximum accuracy.
One cubic inch equals approximately 0.017316 quarts (or more precisely, 0.0173161 quarts). Conversely, one quart contains exactly 57.75 cubic inches. For quick mental math, remember that roughly 58 cubic inches make one quart, so dividing cubic inches by 58 gives a close approximation. For a 350 cubic inch engine: 350 ÷ 58 ≈ 6.03 quarts (actual: 6.06 quarts).
The cubic inch tradition in American automotive stems from the dominance of US manufacturers during the 20th century. Engine displacement became standardized in cubic inches before metric conversion gained traction. Although most modern American vehicles now also display liters on specifications, the cubic inch remains deeply embedded in automotive culture, regulatory documentation, and technical literature. A 350 cubic inch engine is instantly recognized by enthusiasts as approximately 5.74 liters, creating a lasting dual-unit system in the industry.
