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.
A liter is a metric unit of volume used around the world to measure liquids and other fluid substances. It's spelled liter in American English (and litre in British English), and is abbreviated as L or l. One liter is equal to 1,000 milliliters or 0.26417 US gallons, making it a practical size for measuring both household and commercial quantities.
As the base unit of volume in the metric system, the liter is widely used in cooking, grocery labeling, beverages, scientific measurements, and industrial applications. From water bottles and milk cartons to chemical solutions and fuel containers, the liter provides a universal standard that's easy to work with and convert.
Uses: The liter is one of the most widely used volume units globally. In daily life, it's found on drink labels, cleaning products, and food packaging. Everyday items like juice, milk, and bottled water are often sold in whole or fractional liters, making it easy for consumers to understand quantity at a glance.
The liter is used in the kitchen to measure liquids in recipes or for serving sizes. In healthcare, the liter is used for preparing IV fluids, running lab tests, and mixing medications. It’s also used in the auto industry to measure things like engine oil and fuel efficiency. Because it’s easy to understand and widely accepted, the liter continues to be a go-to unit across many areas of daily life.
