The imperial quart is a unit of volume from the imperial system, primarily used in the United Kingdom and some Commonwealth countries. One imperial quart equals 1.13652 liters or 40 imperial fluid ounces, making it larger than the US quart, which holds about 946 milliliters. It's abbreviated as qt and traditionally used to measure liquids and dry goods in household and commercial settings.
In the imperial system, a quart is equal to one-fourth of a gallon and twice the volume of a pint. Though metric units have largely replaced imperial measures in the UK, the quart still appears in older recipes, cooking references, and some product labels—especially in contexts where traditional measurements remain familiar and practical.
Uses: The imperial quart is often seen in vintage British recipes, where it's used to measure liquids like broth, milk, or cream. It also shows up in older cookbooks, measuring jugs, and kitchenware that still use imperial markings. While not as common in everyday packaging today, you might still encounter quarts in contexts like traditional food preparation or when referencing older British standards.
A cubic inch is a unit of volume used in the imperial and U.S. customary systems. It represents the space occupied by a cube, with each side measuring exactly one inch. One cubic inch is equal to 16.387 milliliters or approximately 0.0005787 cubic feet, and it's abbreviated as in³.
The cubic inch is often used to measure smaller volumes in areas like automotive design, mechanical components, and product manufacturing. It’s a go-to unit for things like engine size, compact storage, and custom parts where detailed, space-specific measurements are needed.
Uses: The cubic inch is most widely recognized in the automotive world, where it's often used to express engine size—especially in classic American vehicles. It's also used in engineering and manufacturing for parts design, packaging, and product specifications where precision is important.
In everyday use, you might see cubic inches listed when measuring the internal dimensions of a drawer, estimating the volume of a small box, or comparing product capacities. It remains a trusted unit for capturing volume in tight spaces where accuracy matters.
1 qt (imp) = 69.354553 in³
Let’s say you want to convert 100 qt (imp) to in³.
Using the formula:
100 × 69.354553 = 6935.455 in³
So, 100 qt (imp) is approximately 6935.455 in³.
