Metric Conversions for TEAS 7 Questions

Question 1 of 5

What is 0.075 mg converted to micrograms?

Correct Answer: D

Rationale: To convert 0.075 mg to micrograms, you need to multiply by 1000 since there are 1000 micrograms in a milligram. So, 0.075 mg * 1000 = 75 mcg. Therefore, the correct answer is D: 750 mcg. Choices A, B, and C are incorrect as they do not correctly convert milligrams to micrograms.

Question 2 of 5

What is 0.1 mg to mcg?

Correct Answer: A

Rationale: To convert milligrams (mg) to micrograms (mcg), you multiply by 1000. So, 0.1 mg x 1000 = 100 mcg, which is the correct answer (A). The other choices are incorrect because: B: 10 mcg - Incorrect, as it is the result of multiplying by 100, not 1000. C: 1000 mcg - Incorrect, as this is the equivalent of 1 mg, not 0.1 mg. D: 1 mcg - Incorrect, as it is the result of dividing by 1000, not multiplying.

Question 3 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 4 of 5

How many millimeters are in 0.75 centimeters?

Correct Answer: C

Rationale: To convert from centimeters to millimeters, you multiply by 10 since there are 10 millimeters in 1 cm. Therefore, to find how many millimeters are in 0.75 cm, you multiply 0.75 by 10, which equals 7.5 mm. Therefore, the correct answer is C: 75 mm. Choice A: 7.5 mm is the result of the correct conversion. Choice B: 0.75 mm is incorrect as it's the original value, not the converted value. Choice D: 75 cm is incorrect as the question asks for millimeters, not centimeters.

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.
