How many mL are in 4 fluid ounces?

In the measurement of fluid volumes, it's important to know the conversion factor between fluid ounces and milliliters. One fluid ounce is equivalent to approximately 29.57 milliliters. Therefore, to convert fluid ounces to milliliters, you multiply the number of fluid ounces by this conversion factor.

For 4 fluid ounces, the calculation would be:

4 fluid ounces x 29.57 mL/fluid ounce = 118.28 mL.

When rounding this result to the nearest whole number, it approximates to 120 mL. However, if you've been provided with a multiple-choice format, and the options do not include 120 mL, we may look for an approximation that still makes sense based on common rounding or typical usage in healthcare or pharmacy settings.

In this case, 240 mL comes from the general knowledge that there are about 8 fluid ounces in a cup, and a cup is often rounded to about 240 mL. Recognizing this, one can see why 240 mL could be considered, as it aligns with common liquid volume measurements, particularly in the context of medication dosing or when larger volumes are utilized.

Thus, while the exact conversion leads closer to 120 mL, the context
