1.00 pint of milk has a volume of how many milliliters? (2 pints = 1 quart)
A) 472 mL
B) 530. mL
C) 1000 mL
D) 1890 mL
E) 106 mL
The correct answer and explanation is :
The correct answer is: A) 472 mL
Explanation:
To convert 1.00 pint of milk to milliliters (mL), we need to understand the relationship between pints and milliliters in the U.S. customary system. In the U.S., volume measurements are commonly used in household cooking and food labeling, and one pint has a specific equivalent in metric units.
Conversion Factors:
- 1 U.S. pint = 16 U.S. fluid ounces
- 1 U.S. fluid ounce = 29.5735 mL
So, to convert 1 U.S. pint to milliliters:
[
1 \text{ pint} = 16 \text{ fl oz} \times 29.5735 \text{ mL/fl oz}
]
[
1 \text{ pint} = 473.176 \text{ mL}
]
When rounded to three significant figures, this becomes approximately:
[
1 \text{ pint} \approx 472 \text{ mL}
]
This matches Answer A.
Clarifying the Other Choices:
- B) 530 mL – Too high; this might confuse students with U.K. conversions, where a British pint is approximately 568 mL.
- C) 1000 mL – Equal to 1 liter, which is more than double a U.S. pint.
- D) 1890 mL – Much too high; likely represents an entirely different volume (such as a half gallon or more).
- E) 106 mL – Far too low for a pint; could reflect a misunderstanding or incorrect use of fluid ounce conversions.
Clinical Relevance in Nursing:
Knowing volume conversions like this is crucial in nursing and healthcare settings, particularly when calculating fluid intake/output, administering medications, or converting patient dietary data. A nurse might need to document or assess how much milk a patient consumes, or convert dietary logs from household measures to metric units for accuracy in medical records.
