Teaspoons

A teaspoon (tsp) is a unit of volume in the imperial system, commonly used in cooking and everyday applications. The term "teaspoon" has been used for centuries, and it was originally defined as the volume of a spoon used for stirring tea. Today, teaspoons are widely used in recipes, particularly in the United States and the United Kingdom.

  • 1 US teaspoon (tsp) = 0.0208333 tablespoons (tbsp)
  • 1 US teaspoon (tsp) = 0.0052083 US fluid ounces (fl oz)
  • 1 US teaspoon (tsp) = 0.0020833 pints (pt)

Milliliters (mL)

A milliliter (mL) is a unit of volume in the metric system, equivalent to one-thousandth of a liter (1 L = 1000 mL). The term "milliliter" comes from the Latin words "mille," meaning "thousand," and "liter," which refers to a unit of volume. The milliliter has been used as a standard measurement unit since the metric system's introduction in the late 18th century.

Milliliters are commonly used to measure small volumes of liquids (beverages, cosmetics), such as in cooking (recipes outside the US), medicine (e.g., vaccine doses), and laboratory experiments.

  • 1 mL = 0.202884 teaspoons (tsp)
  • 1 mL = 0.033814 US fluid ounces (fl oz)
  • 1 mL = 0.0351951 UK fluid ounces (fl oz)
  • 1 mL = 0.001 liters (L)
  • 1 mL = 1 cubic centimeter (cm³)
  • 1 mL = 0.0610237 cubic inches (cu in)

 

Converting tsp to mL

The formula to convert teaspoons (tsp) to milliliters (mL) is:

  • US Teaspoons: mL = tsp × 4.92892

Examples:

  1. 2 tsp = 2 × 4.92892 = 9.85784 mL
  2. 5 tsp = 5 × 4.92892 = 24.6446 mL
  3. 10 tsp = 10 × 4.92892 = 49.2892 mL

 

Converting mL to tsp

The formula to convert milliliters (mL) to teaspoons (tsp) is:

  • US Teaspoons: tsp = mL × 0.202884

Examples:

  1. 5 mL = 5 × 0.202884 = 1.01442 tsp
  2. 10 mL = 10 × 0.202884 = 2.02884 tsp
  3. 15 mL = 15 × 0.202884 = 3.04326 tsp
