The gallon (US) is a large unit of volume used in the U.S. customary measurement system. One US gallon is equal to 128 US fluid ounces, or approximately 3.785 liters. It's commonly abbreviated as gal and is often used for measuring larger quantities of liquids in household and commercial settings.
As one of the largest common units for liquid measurement in the United States, the gallon is widely recognized for storing and transporting liquids like milk, water, and gasoline. Its size makes it practical for bulk quantities and remains a standard unit in industries ranging from agriculture to retail packaging.
Uses: In everyday life, the US gallon is most commonly seen on milk jugs, bottled water, and fuel pumps. Whether you're filling up a gas tank or picking up a gallon of juice at the grocery store, this unit is a familiar part of American routines.
Beyond the home, the gallon is used across industries that handle large volumes—such as food service, chemical production, and farming. It's also a staple in recipes or instructions for making batches of beverages, soups, or cleaning solutions. Thanks to its capacity and widespread use, the gallon remains one of the most practical and recognizable units for measuring liquids in bulk.
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.
1 gal = 0.133681 ft³
Let’s say you want to convert 100 gal to ft³.
Using the formula:
100 × 0.133681 = 13.368 ft³
So, 100 gal is approximately 13.368 ft³.
