Metric Conversions for TEAS 7 Questions

Question 1 of 5

What is 0.25 mg to mcg?

Correct Answer: A

Rationale: To convert mg to mcg, we need to multiply by 1000 since 1 mg = 1000 mcg. So, 0.25 mg x 1000 = 250 mcg. Therefore, the correct answer is A: 250 mcg. Choice B, C, and D are incorrect because they do not correctly convert milligrams to micrograms.

Question 2 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.

Question 3 of 5

What is 0.4 grams in milligrams?

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.

Question 4 of 5

What is equivalent to 1 L?

Correct Answer: D

Rationale: The correct answer is D: 1000 milliliters. 1 liter is equivalent to 1000 milliliters. This is because the metric system is based on the powers of 10, so there are 1000 milliliters in 1 liter. Choice A, 1 kilogram, is a unit of mass and not volume. Choice B, 1 quart, is a unit of volume but is not equivalent to 1 liter. Choice C, 1 milliliter, is much smaller than 1 liter, as it would take 1000 milliliters to make up 1 liter.

Question 5 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.
