Metric Conversions for TEAS 7 Questions
Question 1 of 5
What is 0.09 liters in milliliters when converted?
Correct Answer: B
Rationale:
To convert liters to milliliters, you need to multiply by 1,000 since there are 1,000 milliliters in a liter.
Therefore, 0.09 liters x 1,000 = 90 milliliters.
Choice A, 0.09 ml, is incorrect as it represents the original volume in milliliters.
Choices C and D, 900 ml and 9 ml, are incorrect as they miscalculate the conversion from liters to milliliters.
Question 2 of 5
What is the metric prefix for 10^-12 and how does it relate to meters?
Correct Answer: C
Rationale: The prefix 'femto-' stands for 10^-15, making femtometer equal to 10^-15 meters. The incorrect choices are A and B because 'pico-' represents 10^-12 (picometer) and 'nano-' represents 10^-9 (nanometer), respectively.
Choice D is also incorrect as 'pico-' is associated with 10^-12, not 10^-15.
Question 3 of 5
How many grams are in 5 kilograms?
Correct Answer: C
Rationale:
To convert kilograms to grams, you need to multiply by 1000 because there are 1000 grams in a kilogram.
Therefore, 5 kilograms x 1000 grams/kilogram = 5000 grams.
Choices A, B, and D are incorrect because they do not correctly convert kilograms to grams.
Question 4 of 5
Which instrument is used to measure the mass of an object?
Correct Answer: B
Rationale: A balance scale is specifically designed to measure the mass of an object in grams or kilograms. It works based on the principle of balancing the unknown mass against a known mass. A thermometer is used to measure temperature, not mass, so choice A is incorrect.
Choice C, 'scale,' is a bit vague and can refer to different types of scales, but a balance scale is the specific instrument used for measuring mass.
Choice D, 'caliper,' is used for measuring dimensions such as length, width, or thickness, not mass.
Question 5 of 5
What is 0.1 mg to mcg?
Correct Answer: A
Rationale:
To convert milligrams to micrograms, you need to multiply by 1000.
Therefore, 0.1 mg is equal to 100 mcg. This conversion is commonly used in medical calculations.
Choice B (10 mcg) is incorrect because it would be the conversion from milligrams to micrograms if multiplied by 100, not 10.
Choice C (1000 mcg) is incorrect as it would be the conversion from grams to micrograms if multiplied by 1000.
Choice D (1 mcg) is incorrect as it represents the original unit without conversion.
