How many milliliters are there in four fluid ounces? A. 110 ml B. 115 ml C. 120 ml D. 125 ml 3. How many milliliters is in four tablespoons of water? A. 30 ml B. 40 ml C. 50 ml D. 60 ml 4. How many fluid ounces is in one fourth cup? A. one B. two C. three D. four 5. One fourth teaspoon is equivalent to how many milliliters? A. one B. two C. three D. four
The Correct Answer and Explanation is:
Here are the correct answers for each question:
- Four fluid ounces is 120 ml (Answer: C). The conversion factor is 1 fluid ounce = 29.5735 ml, so multiplying by 4 gives approximately 118.3 ml, which rounds to 120 ml.
- Four tablespoons of water is 60 ml (Answer: D). Since 1 tablespoon = 14.7868 ml, multiplying by 4 results in about 59.1 ml, which rounds to 60 ml.
- One-fourth cup is two fluid ounces (Answer: B). A standard cup holds 8 fluid ounces, so dividing by 4 results in 2 fluid ounces.
- One-fourth teaspoon is one milliliter (Answer: A). Since 1 teaspoon = 4.92892 ml, dividing by 4 gives approximately 1.23 ml, which rounds to 1 ml.
Explanation:
Understanding unit conversions in fluid measurements is essential in cooking, chemistry, and medicine. Conversions between tablespoons, teaspoons, milliliters, fluid ounces, and cups are common in recipes and scientific applications.
Milliliters belong to the metric system, used globally, while fluid ounces, tablespoons, and teaspoons are standard in the imperial system, commonly used in the United States. The key to accurate conversions is knowing the fixed ratios between units. For example, since 1 fluid ounce equals 29.5735 milliliters, calculating for multiple ounces follows straightforward multiplication.
Tablespoons are another useful unit, especially in recipes. Since one tablespoon holds approximately 14.7868 milliliters, scaling up allows precise liquid measurement. Similarly, teaspoons play a role in small-scale measurement, and knowing that one teaspoon holds about 4.92892 milliliters ensures accurate ingredient control.
These conversions help maintain consistency in formulations, recipes, and experiments. Whether measuring medication, preparing solutions in a lab, or following a recipe, understanding fluid measurements ensures precision and accuracy in various fields.
