Question 1 of 5
What mnemonic helps in recalling metric conversions?
Correct Answer: A
Rationale: The mnemonic 'King Hector Died By Drinking Chocolate Milk' aids in recalling metric prefixes in order: kilo-, hecto-, deca-, base (meter, liter, gram), deci-, centi-, milli-.
Choice B does not provide a relevant mnemonic for metric conversions.
Choices C and D do not offer a helpful phrase for remembering metric prefixes, making them incorrect.
Question 2 of 5
How many grams are in 1 kilogram?
Correct Answer: C
Rationale: The correct answer is C: 1,000 grams. The metric system follows a logical conversion where 1 kilogram is equal to 1,000 grams. This conversion is a fundamental concept in understanding units of measurement.
Choices A, B, and D are incorrect because they do not accurately reflect the conversion between kilograms and grams. Option A (10 grams) is incorrect as it represents 1/100th of the correct conversion. Option B (100 grams) is also incorrect as it represents 1/10th of the correct conversion. Option D (10,000 grams) is significantly higher than the actual conversion, making it incorrect. Understanding these basic unit conversions is essential for various fields where precise measurements are necessary.
Question 3 of 5
What is the metric equivalent of 1 inch?
Correct Answer: B
Rationale: The correct answer is B: 2.54 cm. One inch is equivalent to 2.54 centimeters in the metric system. This conversion factor is commonly used in converting measurements between the imperial and metric systems.
Choice A (1.54 cm),

Question 4 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.

Rationale:
To convert 0.875 to a fraction, we write it as 875/1000. Simplifying by dividing both the numerator and denominator by 125, we get 7/8.
Therefore, the correct answer is A.
Choice B (8/7) is incorrect as it represents a fraction greater than 1.
Choice C (3/4) and
Choice D (9/10) do not match the correct conversion of 0.875.
