1. What is 0.5 liters in ml?

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

Correct answer: A

Rationale: The correct answer is A: 500 ml. To convert liters to milliliters, you multiply the number of liters by 1000 because 1 liter is equal to 1000 milliliters. Therefore, 0.5 liters x 1000 = 500 milliliters. Choices B, C, and D are incorrect because they do not correctly convert 0.5 liters to milliliters based on the conversion factor of 1000 ml per liter.

2. Convert 1.25 kilograms to grams.

• A. 12.5 grams
• B. 125 grams
• C. 1,250 grams
• D. 1250 mg

Correct answer: C

Rationale: To convert kilograms to grams, you need to multiply by 1000 since there are 1000 grams in a kilogram. Therefore, 1.25 kilograms is equal to 1.25 x 1000 = 1,250 grams. Choices A, B, and D are incorrect because they do not correctly convert kilograms to grams.

3. Convert 0.345 kilometers to meters (m).

• A. 3.45 m
• B. 345 m
• C. 345 cm
• D. 345 m

Correct answer: B

Rationale: To convert kilometers to meters, you need to multiply by 1,000 since there are 1,000 meters in 1 kilometer. Therefore, 0.345 km × 1,000 = 345 meters. Choice A (3.45 m) is incorrect because it is the result of a mathematical error; the decimal point was misplaced. Choice C (345 cm) is incorrect as it represents centimeters, not meters. Choice D (345 m) is a duplicate of the correct answer B.

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

• A. centimeter
• B. cubic meter
• C. cord
• D. centi

Correct answer: A

Rationale: In the metric system, 'cm' stands for centimeter, which is a unit of length equal to 1/100th of a meter. The correct answer is 'centimeter' (A). Choice B, 'cubic meter,' is a unit of volume, not length. Choice C, 'cord,' is not a standard metric unit. Choice D, 'centi,' is a prefix meaning one-hundredth, but 'cm' specifically stands for centimeter, not just the prefix.

5. How many milligrams are in 1 gram?

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

Correct answer: D

Rationale: The correct answer is D: 1,000 mg. This is because 1 gram is equivalent to 1,000 milligrams. To convert grams to milligrams, you multiply by 1,000. Choices A, B, and C are incorrect. Choice A (1 mg) is the smallest unit, and it would take 1,000 of these to make 1 gram. Choice B (10 mg) is also too small, as it would require 100 of these to equal 1 gram. Choice C (100 mg) is closer, but it still falls short of the correct conversion, which is 1,000 mg in 1 gram.
