The imperial teaspoon is a unit of volume used primarily in the United Kingdom and other countries that once followed the imperial measurement system. It's slightly smaller than the US teaspoon, with one imperial teaspoon equal to 4.7355 milliliters. This unit is abbreviated as tsp and has historically appeared in older British cookbooks and kitchenware.
While the imperial system has been largely replaced by the metric system in the UK, many traditional recipes and household items still reference the imperial teaspoon. It's part of a broader set of imperial volume measurements, including tablespoons, fluid ounces, and pints.
Uses: The imperial teaspoon was once a standard unit in British kitchens, used to measure ingredients like sugar, baking powder, and liquid extracts. Though the UK officially uses the metric system today, imperial units still appear in everyday cooking, particularly in family recipes passed down through generations.
You may also see the imperial teaspoon referenced in medication dosages or on packaging in regions that retain imperial labeling. While modern measuring tools often default to metric or US volumes, the imperial teaspoon remains relevant for those following traditional British cooking or converting older recipes accurately.
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.
