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

How many cups are in one pint?

Correct Answer: B

Rationale: The correct answer is B: 2 cups in one pint. A pint is equivalent to 2 cups in the US customary system of measurement. This conversion is based on the fact that 1 pint is equal to 16 fluid ounces, and 1 cup is equal to 8 fluid ounces. Therefore, 16 fluid ounces (1 pint) divided by 8 fluid ounces (1 cup) equals 2 cups. The other choices are incorrect because they do not accurately represent the conversion between pints and cups. Choice A (1 cup) is incorrect as it does not match the conversion factor. Choices C (3 cups) and D (4 cups) are incorrect as they provide values that do not align with the correct measurement relationship between pints and cups.

Question 3 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 4 of 5

What is the metric prefix for 10^-12 and how does it relate to meters?

Correct Answer: C

Rationale: The correct answer is C: femto- (f) = 10^-12 meters. The prefix "femto-" represents 10^-15, not 10^-12. Therefore, choices A and D are incorrect. Choice B, nano- (n) = 10^-12, is incorrect as well because it actually represents 10^-9. The correct relationship is that femto- (f) corresponds to 10^-12 meters, making option C the right choice.

Question 5 of 5

How many milliliters are in 0.5 liters?

Correct Answer: B

Rationale: To convert liters to milliliters, you need to know that 1 liter is equal to 1000 milliliters. So, to find how many milliliters are in 0.5 liters, you multiply 0.5 by 1000, which equals 500 milliliters. Therefore, the correct answer is B: 500 mL. Choice A (50 mL) is incorrect because it is 10 times less than the correct answer. Choice C (5,000 mL) is incorrect because it is 10 times more than the correct answer. Choice D (5 mL) is incorrect because it is 100 times less than the correct answer.
