The imperial fluid ounce is a unit of volume from the imperial measurement system, traditionally used in the United Kingdom and other Commonwealth countries. One imperial fluid ounce is equal to 28.4131 milliliters, which makes it slightly larger than the US fluid ounce (approximately 29.57 mL in the US system). It's commonly abbreviated as fl oz and was widely used for measuring liquids in recipes, packaging, and day-to-day household tasks.
Uses: The imperial fluid ounce was once a standard unit in British kitchens, used to measure ingredients such as milk, oil, and other cooking liquids. While most modern recipes in the UK now use milliliters or grams, many older or traditional recipes still list quantities in fluid ounces. This makes the unit especially relevant for those cooking from classic British cookbooks or following long-standing family recipes.
The imperial fluid ounce still appears on many UK labels, especially for drinks, personal care products, and older medicinal packaging. Whether you're following a traditional recipe or measuring from labeled packaging, knowing how this unit works helps you convert accurately and maintain 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 (imp) = 0.001003 ft³
Let’s say you want to convert 100 fl oz (imp) to ft³.
Using the formula:
100 × 0.001003 = 0.1 ft³
So, 100 fl oz (imp) is approximately 0.1 ft³.
