How many milliliters are in 3 teaspoons?

• A. 10 ml
• B. 5 ml
• C. 15 ml
• D. 20 ml

Answer: (C)

Teaspoon to milliliter conversion is what's being tested. A standard teaspoon equals 5 milliliters, so multiply by the number of teaspoons: 3 × 5 ml = 15 ml. Therefore, 3 teaspoons is 15 milliliters. This aligns with common kitchen and medical measurements. For context, 2 teaspoons would be 10 ml, 1 teaspoon is 5 ml, and 4 teaspoons are 20 ml.
