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.
The imperial pint is a unit of volume from the imperial measurement system, traditionally used in the United Kingdom and some Commonwealth countries. One imperial pint equals 568.261 milliliters, making it larger than the US pint, which holds about 473 milliliters. It's abbreviated as pt and is a familiar measure in British cooking, food packaging, and beverage servings.
Historically, the imperial pint was used as a standard for measuring liquids and dry ingredients in recipes. It equals 20 imperial fluid ounces and exactly half of an imperial quart. While the UK now officially uses the metric system, the imperial pint remains widely recognized and commonly used, especially when it comes to drinks and dairy products.
Uses: The imperial pint is still widely used in the UK today, most notably in pubs and grocery stores. A pint of beer, cider, or milk is a standard serving size, and many packaged drinks and dairy items still display quantities in pints. It's also a common unit in older British recipes and cookbooks, where it's used to measure liquids like broth, cream, or water.
Even though the UK has officially adopted the metric system, the imperial pint still holds a strong place in everyday British life. From classic recipes to a pint of beer at the pub, it remains a trusted and widely recognized measurement that many people continue to rely on.
