1. What is 0.075 mg in mcg?

• A. 0.075 mcg
• B. 7.5 mcg
• C. 0.75 mcg
• D. 750 mcg

Correct answer: D

Rationale: To convert milligrams to micrograms, you need to multiply by 1000 since 1 mg = 1000 mcg. Therefore, 0.075 mg equals 75 * 1000 = 750 mcg. The correct answer is 750 mcg. Choices A, B, and C are incorrect because they do not apply the correct conversion factor of 1000. It is essential to understand these conversions, especially in medical settings where accurate dosing is crucial to avoid errors and ensure patient safety.

2. Which basic SI conversion is incorrect?

• A. 1 cm = 10 mm
• B. 1 m = 100 cm
• C. 1 km = 1000 m
• D. 1 g = 100 mg

Correct answer: D

Rationale: The correct SI conversion for grams (g) to milligrams (mg) is 1 g = 1000 mg, not 100 mg. Therefore, option D is incorrect. Option A is correct as 1 cm is equal to 10 mm, option B is correct as 1 m equals 100 cm, and option C is correct as 1 km is equivalent to 1000 m. Understanding these basic SI conversions is essential for accurate measurements and calculations in various scientific fields.

3. The prefix 'milli' stands for 0.001 (10^-3). This means, 1 mm is the same as:

• A. 0.01 m
• B. 0.001 m
• C. 0.1 m
• D. 1 m

Correct answer: B

Rationale: The correct answer is B: '0.001 m.' The prefix 'milli' represents a factor of 10^-3, which means one millimeter (mm) is equivalent to 0.001 meters (m). Therefore, 1 mm is equal to 0.001 m. Choice A, '0.01 m,' is incorrect as it represents 0.01 meters, not 0.001 meters. Choice C, '0.1 m,' is incorrect because it stands for 0.1 meters, which is 10 times greater than 1 mm. Choice D, '1 m,' is incorrect as it represents 1 meter, which is 1000 times greater than 1 mm.

4. What does 'kg' stand for in the metric system?

• A. kilogram
• B. keg
• C. kroner
• D. kraken

Correct answer: A

Rationale: 'kg' stands for kilogram, the unit of mass equal to 1,000 grams. In the metric system, 'kg' specifically represents the unit of mass, making 'kilogram' the correct choice. The other choices, 'keg,' 'kroner,' and 'kraken,' do not represent the standard unit of mass in the metric system and are therefore incorrect.

5. What is 1500 milliliters in liters?

• A. 1.5 liters
• B. 0.15 liters
• C. 15 liters
• D. 0.015 liters

Correct answer: A

Rationale: To convert milliliters to liters, you need to divide by 1000 since there are 1000 milliliters in 1 liter. Therefore, 1500 milliliters divided by 1000 equals 1.5 liters, making option A the correct answer. Option B, 0.15 liters, is incorrect as it would be the conversion of 150 milliliters. Option C, 15 liters, is incorrect because it would be the conversion of 15,000 milliliters. Option D, 0.015 liters, is incorrect as it would be the conversion of 15 milliliters.
