Cubic Foot (ft³)
A cubic foot (ft³) is a unit of volume in the imperial and US customary systems, defined as the amount of space enclosed by a cube with one-foot sides. It originated in English-speaking regions where it became a standard for measuring materials and space, especially in construction and trade. Today, the cubic foot remains common in American industries such as real estate, heating and cooling (HVAC), and the measurement of natural gas. It is equal to about 28.316 liters, allowing for practical use in both domestic and industrial settings. Even though most of the world uses metric units, the cubic foot maintains its significance in various technical and commercial fields.
