Teaspoons to ML FAQ
Answers to the most frequently asked questions about volume conversions, cooking measurements, and medical dosing.
The volume of a teaspoon depends on the measurement system. A US customary teaspoon is approximately 4.93 ml, a Metric teaspoon is exactly 5 ml, and a UK Imperial teaspoon is approximately 5.92 ml.
Yes, in the Metric system, 5 ml is exactly equal to 1 teaspoon. This is the standard used in most countries worldwide and for medical dosing. However, a US teaspoon is slightly smaller at 4.93 ml.
A US customary teaspoon is defined as 4.92892 ml, while a traditional UK Imperial teaspoon is 5.91939 ml. Modern UK recipes and medicine often use the Metric standard of 5 ml, but older recipes may reference the Imperial size.
If you don’t have a measuring spoon, you can estimate using your hand: the tip of your index finger (from the first joint to the tip) is roughly equivalent to 1 teaspoon (5 ml). For better accuracy, especially with medicine, use a proper syringe or measuring cup.
