A teaspoon (US) is a unit of volume measurement commonly used in American kitchens and food labeling. It is part of the US customary system and is typically abbreviated as "tsp." One US teaspoon is defined as exactly 4.92892 milliliters. It's also equivalent to one-third of a US tablespoon and one forty-eighth of a US cup.
This unit is frequently seen in recipes for small quantities of ingredients like salt, baking powder, or vanilla extract. It's also a common part of household measuring spoon sets, which usually include ¼, ½, and 1 teaspoon sizes.
Uses: The US teaspoon is widely used in both culinary and non-culinary contexts across the United States. The US teaspoon is a commonly used unit in everyday cooking, especially in baking, where accurate measurements of ingredients like spices, extracts, and baking powder are key to getting consistent results. Outside the kitchen, this small but essential unit is frequently used in healthcare as a standard measure for liquid medications, particularly when dosing for children. While medical professionals usually recommend milliliters for precision, many over-the-counter medicines in the US still refer to teaspoons as a practical reference.
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.
