1. What is 0.5 liters converted to milliliters?

• A. 50 ml
• B. 500 ml
• C. 5 ml
• D. 0.5 ml

Correct answer: B

Rationale: To convert liters to milliliters, you need to multiply the number of liters by 1000 because there are 1000 milliliters in 1 liter. Therefore, 0.5 liters converts to 500 milliliters. Choice A (50 ml) is incorrect as it is the result of multiplying by 10 instead of 1000. Choice C (5 ml) is incorrect as it is the result of dividing by 10 instead of multiplying by 1000. Choice D (0.5 ml) is incorrect as it represents the original quantity in milliliters, not the conversion from liters.

2. How many mcg are there in 0.2 mg?

• A. 20 mcg
• B. 200 mcg
• C. 2000 mcg
• D. 2 mcg

Correct answer: B

Rationale: To convert milligrams to micrograms, you need to multiply by 1000 since 1 mg is equal to 1000 mcg. Therefore, 0.2 mg is equivalent to 200 mcg. It is crucial to understand this conversion to ensure precise medication dosages. Choice A is incorrect because it does not account for the conversion factor of 1000 between milligrams and micrograms. Choice C is incorrect as it represents the conversion of grams to micrograms. Choice D is incorrect as it does not consider the conversion factor from milligrams to micrograms.

3. How many micrograms are in 1 milligram?

• A. 1 µg
• B. 10 µg
• C. 100 µg
• D. 1,000 µg

Correct answer: D

Rationale: The correct answer is D: 1,000 µg. To convert milligrams to micrograms, you need to multiply by 1,000 because there are 1,000 micrograms in 1 milligram. Choices A, B, and C are incorrect because they do not correctly convert milligrams to micrograms. 1 milligram is equal to 1,000 micrograms, making choice D the right answer.

4. How many grams are in one kilogram?

• A. 100 grams
• B. 1000 grams
• C. 500 grams
• D. 2000 grams

Correct answer: B

Rationale: The correct answer is B: 1000 grams. This is because by definition, 1 kilogram is equal to 1000 grams. Choice A, 100 grams, is incorrect as it underestimates the actual conversion. Choice C, 500 grams, and Choice D, 2000 grams, are also incorrect as they do not align with the correct conversion factor of 1 kilogram to 1000 grams.

5. How many centimeters are in 1 inch?

• A. 2.54 cm
• B. 3 cm
• C. 2 cm
• D. 1 cm

Correct answer: A

Rationale: The correct answer is A: 2.54 cm. One inch is equivalent to 2.54 centimeters. This conversion factor is commonly used when converting measurements between the metric and imperial systems. Choice B (3 cm) is incorrect as it is not the accurate conversion factor for 1 inch. Choice C (2 cm) is also incorrect as it does not reflect the correct conversion. Choice D (1 cm) is incorrect as it inaccurately states the conversion value for 1 inch.
