A fluid ounce (US) is a unit of volume used to measure liquids in the U.S. customary system. It's abbreviated as fl oz and is commonly seen in cooking, nutrition labeling, and liquid packaging. One US fluid ounce is defined as 1/128 of a US gallon, which equals exactly 29.5735 milliliters.
Despite the term "ounce" also being used for weight, a fluid ounce specifically measures liquid volume. It's important to distinguish the two, especially in recipes or products where both liquid and solid measurements appear. The US fluid ounce is a standard unit across many industries, from beverages and sauces to cleaning products and personal care items,
Uses: The fluid ounce is widely used in everyday life throughout the United States. In the kitchen, it shows up in recipes for measuring water, milk, oil, and other liquids. You'll also find it on nutrition labels, drink containers, and liquid medicine bottles. Most bottled drinks sold in the U.S., from soda cans to sports drinks, are labeled in fluid ounces.
Outside the kitchen, fluid ounces are also used to measure everyday products like shampoo, lotion, and household cleaners. Packaging labels often list fluid ounces to help shoppers gauge how much liquid is inside each bottle. In pharmacies, you may still see fluid ounces on medication packaging, though many prescriptions now use milliliters for greater accuracy and consistency.
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 fl oz = 0.001044 ft³
Let’s say you want to convert 100 fl oz to ft³.
Using the formula:
100 × 0.001044 = 0.104 ft³
So, 100 fl oz is approximately 0.104 ft³.
