Metric Conversions for TEAS 7 Questions

Question 1 of 5

Which instrument is used to measure the mass of an object?

Correct Answer: B

Rationale: The correct answer is B: balance scale. A balance scale is used to measure the mass of an object by comparing it to a set of known masses. It works on the principle of equilibrium, where the object's mass is balanced by adding or removing known masses until the scale is level. Choice A, thermometer, measures temperature, not mass. Choice C, scale, is a general term and could refer to different types of scales, but a balance scale specifically measures mass. Choice D, caliper, is used to measure dimensions such as length or diameter, not mass. Therefore, the balance scale is the correct choice for measuring mass accurately.

Question 2 of 5

What is 0.025 mg in mcg?

Correct Answer: A

Rationale: To convert mg to mcg, you need to multiply by 1000. Therefore, 0.025 mg x 1000 = 25 mcg. The correct answer is A (25 mcg). Choice B (250 mcg) is incorrect as it incorrectly multiplies by 10 instead of 1000. Choice C (2.5 mcg) is incorrect as it drops a zero from the conversion. Choice D (0.25 mcg) is incorrect as it adds an extra zero to the answer.

Question 3 of 5

How many ounces are in one pint?

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.

Question 4 of 5

Where was the metric system developed?

Correct Answer: B

Rationale: The correct answer is B: France. The metric system was developed in France during the French Revolution in the late 18th century. The French Academy of Sciences proposed the system to standardize measurements for scientific and commercial purposes. France played a significant role in promoting and spreading the use of the metric system worldwide. Germany (A), Italy (C), and Spain (D) did not have a direct role in the development of the metric system.
