Metric Conversions for TEAS 7 Questions

Question 1 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 2 of 5

Convert 0.20 liters to milliliters. What is the equivalent volume?

Correct Answer: A

Rationale: To convert 0.20 liters to milliliters, we know that 1 liter is equal to 1000 milliliters. Therefore, 0.20 liters = 0.20 x 1000 = 200 milliliters. So, the correct answer is A: 200 ml. Choice B (20 ml) is incorrect as it represents 0.02 liters. Choice C (2 ml) is incorrect as it represents 0.002 liters. Choice D (2000 ml) is incorrect as it is the result of incorrectly multiplying 0.20 liters by 1000 twice.

Question 3 of 5

What is the equivalent of 1 nanometer (nm) in meters (m)?

Correct Answer: A

Rationale: To convert nanometers to meters, we need to remember that nano- is a prefix meaning 10^-9. Therefore, 1 nanometer is equal to 10^-9 meters. So, the correct answer is A: 10^-9 meters. Explanation for why other choices are incorrect: - B: 10^-6 meters is the equivalent of a micrometer, not a nanometer. - C: 10^-12 meters is the equivalent of a picometer, which is smaller than a nanometer. - D: 10^-15 meters is the equivalent of a femtometer, which is much smaller than a nanometer.

Question 4 of 5

What is the base unit for liquid volume in the metric system?

Correct Answer: B

Rationale: The correct answer is B: Liters. Liters are the base unit for liquid volume in the metric system because they are used to measure larger volumes, making them more practical for everyday use. Milliliters are a smaller unit derived from liters, making them not the base unit. Gallons are not part of the metric system; they are commonly used in the imperial system. Choosing Liters again reinforces that it is the correct base unit for liquid volume in the metric system.

Question 5 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.
