Metric Conversions for TEAS 7 Questions

Question 1 of 5

Convert 345 kilometers to meters (m).

Correct Answer: B

Rationale: To convert kilometers to meters, you multiply by 1000 since 1 kilometer is equal to 1000 meters. Therefore, 345 kilometers x 1000 = 345,000 meters. Choice A is incorrect as it doesn't account for the conversion factor. Choice C is incorrect as it adds an extra zero. Choice D is incorrect as it adds two extra zeros. Choice B is the correct answer as it correctly converts 345 kilometers to meters by multiplying by 1000.

Question 2 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 3 of 5

What is the equivalent of 0.3 mg in mcg?

Correct Answer: A

Rationale: To convert milligrams (mg) to micrograms (mcg), you need to multiply by 1000 since 1 mg = 1000 mcg. Therefore, 0.3 mg would be equal to 0.3 * 1000 = 300 mcg. This makes choice A (300 mcg) the correct answer. Choices B, C, and D are incorrect because they do not apply the correct conversion factor of 1000 to convert from mg to mcg, leading to incorrect values.

Question 4 of 5

What does 'kg' stand for in the metric system?

Correct Answer: A

Rationale: The correct answer is A: kilogram. In the metric system, 'kg' stands for kilogram, which is the unit of mass. The prefix 'kilo-' denotes 1000, so a kilogram is equal to 1000 grams. This is the standard unit used to measure mass in the metric system. B: keg is incorrect as it is a container for storing liquids, not a unit of measurement. C: kroner is the currency used in Norway and Denmark, not a unit of measurement in the metric system. D: kraken is a mythical sea monster and not related to any unit of measurement. Therefore, the correct choice is A as it corresponds to the standard unit for mass in the metric system.

Question 5 of 5

Which of the following is equal to 0.13 inches?

Correct Answer: C

Rationale: To convert a decimal to inches, we know that 1 inch is equal to 1.0. So, 0.13 inches can be written as 0.13 * 1 inch which equals 0.13 inches. A: 0.013 inches - Incorrect, this is a smaller value than 0.13 inches. B: 1.3 inches - Incorrect, this is a larger value than 0.13 inches. D: 13 inches - Incorrect, this is a significantly larger value than 0.13 inches. Therefore, the correct answer is C as 0.13 inches is the equivalent decimal value.
