How many milliliters are in 2 teaspoons?

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

Answer: (B)

Converting between teaspoons and milliliters uses the standard that 1 teaspoon equals 5 milliliters. So two teaspoons are 2 × 5 mL = 10 mL. This relationship is handy in both cooking and medical dosing, where memorizing 5 mL per teaspoon helps quick conversions. For reference, 5 mL is just one teaspoon, 15 mL is one tablespoon, and 20 mL equals four teaspoons (or one tablespoon plus one teaspoon). Therefore, the amount is 10 mL.
