Teaspoons Converter

Teaspoon

A teaspoon (tsp) is a small US customary unit of volume used mainly for measuring ingredients in cooking and beverages. One US teaspoon equals one-third of a tablespoon or about 4.93 milliliters, making it ideal for small additions like salt, spices, extracts, or medicine doses. It’s one of the most common measurements in recipes and is included in almost every set of measuring spoons.

Because metric measurements are widely used outside the United States, converting teaspoons to milliliters, tablespoons, or cups can be helpful when following international recipes. A conversion tool ensures accuracy so results remain consistent in the kitchen.

Teaspoons in Everyday Use

Teaspoons are perfect for small but important measurements — a little too much or too little can change the taste or texture of a dish. You’ll also find teaspoons used on product labels, especially for nutritional information, as serving sizes are often listed in teaspoon amounts.

Since one teaspoon is just under 5 milliliters, knowing precise conversions helps avoid rounding errors when translating recipes or dosage instructions. Whether preparing a meal, mixing a drink, or measuring medicine, understanding teaspoon equivalents helps make everyday tasks easier and more accurate.
