In the metric system, 4 fluid drams (fl dr) is equivalent to which of the following?

• A. 4 mL
• B. 40 mL
• C. 14.8 mL
• D. 1.2 mL

Answer: (C)

Verified step by step guidance

1. Understand that the problem asks for the conversion of 4 fluid drams (fl dr) into milliliters (mL), which are both units of volume but from different measurement systems.
2. Recall the conversion factor between fluid drams and milliliters. One fluid dram is defined as approximately 3.7 milliliters. This is a standard conversion used in the metric system.
3. Set up the conversion calculation using the formula: \(\text{Volume in mL} = \text{Volume in fl dr} \times \text{Conversion factor}\).
4. Substitute the given values into the formula: \(\text{Volume in mL} = 4 \times 3.7\) mL.
5. Perform the multiplication to find the equivalent volume in milliliters, which will give you the answer closest to 14.8 mL.
