How much is 1 tablespoon in milliliters?

The correct conversion of 1 tablespoon is 15 milliliters. Therefore, when looking at the options given, the most accurate answer is that 1 tablespoon is equivalent to 15 ml. This standard measurement is widely used in cooking and nutrition to ensure consistency in recipes and dietary guidelines. Understanding this conversion is important for tasks such as medication administration, where precise measurements are vital.

While some options may appear close, like 30 ml, it is actually incorrect as that would represent 2 tablespoons, not 1. Similarly, both 10 ml and 5 ml significantly underestimate the amount in a tablespoon. Knowing the accurate conversion helps in both practical applications and assessments related to medication administration and culinary measurements.
