1. 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.

2. How many milliliters are in a tablespoon?

• A. 10 ml
• B. 15 ml
• C. 5 ml
• D. 20 ml

Correct answer: B

Rationale: The correct answer is B: 15 ml. One tablespoon is equivalent to 15 milliliters. The conversion factor for tablespoons to milliliters is 1 tablespoon = 15 milliliters. Choice A (10 ml) is incorrect because it is not the standard conversion for a tablespoon. Choice C (5 ml) is incorrect as it is too low for a tablespoon. Choice D (20 ml) is incorrect as it is too high for a tablespoon. Therefore, the correct conversion is 15 milliliters for one tablespoon.

3. What is 0.1 mg to mcg?

• A. 100 mcg
• B. 10 mcg
• C. 1000 mcg
• D. 1 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.

4. How many kilometers (km) is equivalent to 1,000 meters?

• A. 0.1 km
• B. 1 km
• C. 10 km
• D. 0.01 km

Correct answer: B

Rationale: To convert meters to kilometers, the conversion factor is 1 kilometer = 1,000 meters. Therefore, to find how many kilometers are in 1,000 meters, you divide 1,000 by 1,000, which equals 1 kilometer. Choice A (0.1 km), Choice C (10 km), and Choice D (0.01 km) are incorrect because they do not correctly represent the conversion of 1,000 meters to kilometers.

5. What is the official name of the metric system?

• A. International Measurement System
• B. International System of Units
• C. Metric Unit System
• D. Measurement System of Units

Correct answer: B

Rationale: The official name of the metric system is the International System of Units (SI). The International System of Units is a globally recognized standard for measurement. Choice A, 'International Measurement System,' is incorrect as it does not accurately reflect the official name. Choice C, 'Metric Unit System,' while related to the metric system, is not the precise official name. Choice D, 'Measurement System of Units,' is a mix-up of terms and does not represent the correct official name of the metric system.
