1ml equals half a teaspoon

Answer 1

No

1 milliliter equals 0.202 US teaspoons.

1 teaspoon is 4.928 milliliters

Answer 2

Again this is an answer from the UK.

We normally say that 5mls is one teaspoon.

Therefore we would answer your question that 1ml is 1/5th of a teaspoon.

Answer 3

There are 5 ml in a teaspoon, so to convert to 1 and 1/2 tsp, you would multiply 5 x 1.5, which = 7.5 ml.

Answer 4

1 ml is 1/5 of a teaspoon. 2.5 ml is 1/2 a teaspoon.
