A cubic foot is a unit of volume used in the imperial and U.S. customary measurement systems. It represents the space occupied by a cube with sides that are each one foot long. One cubic foot is equal to 1,728 cubic inches or approximately 28.3168 liters. It's commonly abbreviated as ft³ and is typically used for measuring larger volumes, especially in construction, storage, and shipping.
Unlike units like milliliters or teaspoons, the cubic foot is designed for measuring bulk quantities or physical space. The cubic foot is often used when measuring things like the volume of a box, the size of a freezer, or how much air moves through a ventilation system. It serves as a practical unit for working with larger volumes in everyday and industrial settings.
Uses: The cubic foot is widely used in industries where space and volume matter. It's commonly seen in construction when calculating the volume of concrete, soil, or insulation. In shipping and logistics, it's used to estimate the capacity of containers and freight. Appliances like refrigerators, freezers, and ovens often list their internal capacity in cubic feet to help buyers compare storage space.
In everyday use, the cubic foot might show up when measuring a moving box's size, determining garage storage space, or calculating how much mulch is needed for a garden bed. It remains a trusted unit for real-world measurements where larger volumes are involved.
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 ft³ = 1727.993361 in³
Let’s say you want to convert 100 ft³ to in³.
Using the formula:
100 × 1727.993361 = 172799.336 in³
So, 100 ft³ is approximately 172799.336 in³.
