Metric Conversions for TEAS 7 Questions

Question 1 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.

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 centimeters are in one millimeter?

Correct Answer: B

Rationale: The correct answer is B: 0.1 cm. 1 millimeter is equal to 0.1 centimeters because there are 10 millimeters in 1 centimeter. To convert millimeters to centimeters, you divide by 10. Choice A (1/100 cm) is incorrect because 1 millimeter is not equal to 1/100 of a centimeter. Choice C (1 cm) is incorrect because 1 millimeter is smaller than 1 centimeter. Choice D (10 cm) is incorrect because 1 millimeter is not equal to 10 centimeters; it is only 0.1 centimeters.

Question 4 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 5 of 5

10^6 m can be expressed as ____.

Correct Answer: A

Rationale: Certainly! To express 10^6 m in simpler terms, we need to convert meters to kilometers. 1 kilometer is equal to 1000 meters. Therefore, 10^6 m = 1,000,000 m = 1 km. Option A is correct because 1 kilometer is the equivalent of 10^6 meters. Options B, C, and D are incorrect because they represent larger units of measurement than meters. Megameter is 1,000,000 meters, gigameter is 1,000,000,000 meters, and terameter is 1,000,000,000,000 meters, making them larger than 10^6 meters.
