Convert 16.9 fluid ounces to milliliters. (Round your answer to the nearest tenth.)
The Correct Answer and Explanation is:
To convert fluid ounces to milliliters, we can use the conversion factor that 1 fluid ounce is approximately equal to 29.5735 milliliters. Therefore, to convert 16.9 fluid ounces to milliliters, we can follow this calculation:
[
\text{Milliliters} = \text{Fluid Ounces} \times \text{Conversion Factor}
]
Substituting the values we have:
[
\text{Milliliters} = 16.9 \, \text{fluid ounces} \times 29.5735 \, \text{mL/fluid ounce}
]
Calculating this gives:
[
\text{Milliliters} = 16.9 \times 29.5735 \approx 499.74715 \, \text{mL}
]
Rounding this value to the nearest tenth, we get:
[
\text{Milliliters} \approx 499.7 \, \text{mL}
]
Explanation:
Understanding how to convert fluid ounces to milliliters is essential, especially in fields such as nursing, cooking, and chemistry, where precise measurements are crucial. The conversion factor between these two units is key to performing accurate calculations. In the U.S., fluid ounces are commonly used to measure liquid volumes in recipes and nutritional labels, while milliliters are the standard in scientific settings, particularly in medicine and pharmaceuticals.
When converting units, it’s important to maintain the integrity of the data. Rounding is often necessary when dealing with measurements to simplify the data while keeping it within an acceptable range of accuracy. In this case, rounding to the nearest tenth provides a practical figure that is easy to use in further calculations or when conveying information.
Moreover, knowing how to perform such conversions can help healthcare professionals ensure that medications, which are often dosed in milliliters, are correctly measured based on the volumes specified in fluid ounces on packaging or instructions. This conversion also aids in understanding and comparing nutritional content across different countries, where serving sizes may be labeled in various units of measure. Thus, mastering this conversion is not just about numbers; it’s about ensuring safety and efficacy in practical applications.
