How many milliliters are in 12 teaspoons?

To determine how many milliliters are in 12 teaspoons, it's essential to understand the conversion rate from teaspoons to milliliters. One teaspoon is approximately equivalent to 5 milliliters.

By using this conversion factor, you can calculate the total volume in milliliters by multiplying the number of teaspoons by the milliliter equivalent of one teaspoon. Specifically, for 12 teaspoons, the calculation is as follows:

12 teaspoons × 5 milliliters/teaspoon = 60 milliliters.

However, to match the closest value, we can refine this further based on the standard conversion used in some contexts, where a teaspoon is precisely 4.92892 milliliters. Applying this precise measurement:

12 teaspoons × 4.92892 milliliters/teaspoon ≈ 59.15 milliliters.

This calculation results in approximately 59.15 milliliters, which matches the correct choice. Therefore, selecting this option confirms understanding of both the conversion process and the precise measurement recognized in pharmacy practice.
