About these units
Liter (L, l)
The liter is one of the most widely used units of volume worldwide, defined as the volume of a cube measuring 10 centimeters on each side, making 1 L = 1,000 cubic centimeters = 1 cubic decimeter. Despite not being an SI base unit, it is fully accepted for use with the SI system due to its universal practicality. The liter occupies a sweet spot: large enough to measure beverages, fuel, and household liquids, yet small enough for precise laboratory use. Its intuitive scale simplifies everyday tasks—recipes, medical dosages, aquarium capacities, and fuel economy are all naturally expressed in liters. In science, the liter's alignment with the metric system makes it indispensable for expressing fluid volumes, solution concentrations (L in mol/L), and gas quantities under standard conditions. Industrial systems use liters for chemical processing, water treatment, and food production, making it a cornerstone of modern volume measurement.
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.
