About This Calculator
The Teaspoons to Milliliters (tsp to ml) Converter is a free online tool that converts volume measurements from teaspoons to milliliters instantly. Whether you are following a recipe with US or UK measurements, scaling ingredients for cooking and baking, or converting between metric and imperial volume systems, this converter provides accurate and reliable results using the standard international conversion factor.
One teaspoon equals 5 milliliters under the international standard, which is the most commonly used conversion in modern recipes. However, variations exist: the US customary teaspoon is 4.93 ml, and the Australian teaspoon is 5 ml. This converter uses 5 ml per teaspoon, making it suitable for the majority of international recipes and food labeling standards.
To convert teaspoons to milliliters, multiply the number of teaspoons by 5. For example, if a recipe calls for 3 teaspoons of vanilla extract, that equals 3 × 5 = 15 ml. Our calculator handles both whole numbers and decimal values, making it ideal for precise ingredient measurement in any kitchen.
Common uses: Converting recipe measurements from US/UK cookbooks, scaling ingredient quantities, calculating liquid medication doses (common in 5 ml and 10 ml doses), mixing cleaning solutions, and general volume conversion between imperial and metric systems.
