Metric Conversions for TEAS 7

Correct Answer: B

Rationale: The correct answer is B: 2.54 cm. To convert inches to centimeters, we use the conversion factor 1 inch = 2.54 cm. This conversion factor is based on the definition of an inch and a centimeter. Therefore, 1 inch is equivalent to 2.54 centimeters. Choice A (1.54 cm) is incorrect as it is not the correct conversion factor for inches to centimeters. Choice C (3.54 cm) and Choice D (4.54 cm) are also incorrect as they do not correspond to the accurate conversion of inches to centimeters.

Correct Answer: B

Rationale: The correct answer is B: 16 ounces. One pint is equivalent to 16 fluid ounces. This is a standard conversion in the US customary system. To arrive at this answer, you need to know that there are 2 cups in a pint and 8 fluid ounces in a cup, giving a total of 16 ounces in one pint. Choice A (12 ounces) is incorrect because it does not match the standard conversion of one pint to 16 ounces. Choice C (8 ounces) is incorrect as it represents the amount in one cup, not a pint. Choice D (20 ounces) is incorrect as it exceeds the standard conversion for one pint.

Correct Answer: A

Rationale: To convert grams to milligrams, you multiply by 1000 since 1 gram = 1000 milligrams. Therefore, 0.4 grams x 1000 = 400 mg. Choice A (400 mg) is correct. Choices B, C, and D are incorrect because they do not follow the correct conversion factor of 1 gram = 1000 milligrams.

Correct Answer: A

Rationale: To convert liters to milliliters, you multiply by 1000 since 1 liter = 1000 ml. Therefore, 0.5 liters x 1000 = 500 ml. Thus, the correct answer is A (500 ml). Choice B (50 ml) is incorrect as it is 10 times smaller than the correct answer. Choice C (5 ml) is incorrect as it is 100 times smaller than the correct answer. Choice D (0.5 ml) is incorrect as it is the same value in milliliters, not the conversion of liters to milliliters.
