5 ml equals how many teaspoons?

• A. 0.5 tsp
• B. 1 tsp
• C. 2 tsp
• D. 3 tsp

Answer: (B)

Understanding how milliliters relate to teaspoons is the key idea here. A standard teaspoon holds 5 milliliters, so 5 ml is exactly 1 teaspoon. That’s why the correct amount is one teaspoon. If you compare to other options, they would represent different volumes—half a teaspoon is about 2.5 ml, two teaspoons is about 10 ml, and three teaspoons is about 15 ml—not equal to 5 ml.
