About these units
Cubic Foot (ft³)
A cubic foot equals 28.31684659 liters, representing the volume of a cube one foot on each side. It is widely used in construction, real estate, natural gas metering, and HVAC systems. Room ventilation rates, airflow in ducts, and gas consumption often use cubic feet or cubic feet per minute (CFM). Storage capacity for freezers, shipping containers, and building materials also frequently uses this unit. The cubic foot's relationship to the foot makes it practical in industries where imperial length units still dominate.
Cup (US) (cup (US))
A US cup equals 8 fluid ounces, or approximately 236.588 mL. It is indispensable in American cooking, baking, and beverage measurement. Although not an SI unit, the cup remains deeply entrenched in recipes, cookbooks, and kitchen culture. Its intuitive size makes it ideal for measuring flour, sugar, liquids, and many everyday ingredients. American cups differ from metric and UK cups, leading to variation across international recipes, but within the US culinary tradition, the cup is a central volumetric tool.
