How many ounces are equal to 90 milliliters? A) 3 ounces B) 30 ounces C) 90 ounces D) 120 ounces
The Correct Answer and Explanation is :
To convert milliliters (mL) to ounces (oz), we can use the conversion factor that 1 ounce is approximately equal to 29.5735 milliliters. Therefore, to find out how many ounces are in 90 milliliters, we can use the following formula:
[
\text{Ounces} = \frac{\text{Milliliters}}{29.5735}
]
Plugging in the value:
[
\text{Ounces} = \frac{90 \text{ mL}}{29.5735} \approx 3.04 \text{ oz}
]
Rounding to two decimal places, we find that 90 milliliters is approximately equal to 3.04 ounces.
Answer:
The closest option to this calculation is A) 3 ounces.
Explanation:
Understanding the conversion between milliliters and ounces is crucial, especially in contexts like cooking, medicine, and science, where precise measurements are often needed. The metric system, which includes milliliters, is widely used around the world, while the imperial system, which includes ounces, is prevalent in the United States.
- Metric vs. Imperial System: The metric system is decimal-based, making calculations straightforward. One milliliter is one-thousandth of a liter, whereas ounces belong to the imperial system, where there are 8 ounces in a cup and 16 ounces in a pint. This difference in systems can lead to confusion, especially when recipes or medication dosages are converted.
- Practical Applications: In cooking, knowing the conversion helps ensure that recipes turn out as intended, especially in baking, where precision is critical. In healthcare, accurate dosage calculations can be lifesaving. For example, a liquid medication measured in milliliters might need to be converted to ounces for patient instructions.
- Conversion Factor: The importance of the conversion factor (29.5735 mL per ounce) cannot be understated, as it serves as the bridge between these two systems. By using it accurately, one can ensure proper conversions, leading to better outcomes in various applications.
In conclusion, 90 milliliters is approximately 3 ounces, making option A the correct answer. Understanding this conversion is vital across many fields and practical situations.
