1. How many milligrams (mg) are equal to 1 gram?

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

Correct answer: B

Rationale: To convert grams to milligrams, you need to multiply by 1,000 because there are 1,000 milligrams in 1 gram. Therefore, 1 gram × 1,000 = 1,000 milligrams. Choice A (100 mg) is incorrect as it represents 0.1 grams, not 1 gram. Choice C (1 mg) is incorrect as it represents a fraction of a gram. Choice D (10,000 mg) is incorrect as it is 10 times more than the correct conversion.

2. What is 0.5 liters in ml?

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

Correct answer: A

Rationale: To convert liters to milliliters, you need to multiply by 1000 since 1 liter is equal to 1000 milliliters. Therefore, 0.5 liters equals 500 milliliters. This conversion is commonly used in various fields such as cooking, medicine, and science. Choice B, 50 ml, is incorrect as it represents 0.05 liters, not 0.5 liters. Choice C, 5 ml, is even smaller and represents 0.005 liters. Choice D, 0.5 ml, is incorrect as it is a tenth of the correct conversion.

3. What is the conversion factor from milliliters to liters?

• A. 0.001 liters
• B. 0.01 liters
• C. 1 liter
• D. 10 liters

Correct answer: A

Rationale: To convert milliliters to liters, you need to divide by 1000 since there are 1000 milliliters in a liter. Therefore, the correct conversion factor is 0.001 liters (1 liter = 1000 milliliters). Choice B (0.01 liters) is incorrect as it suggests dividing by 100, which is not the correct conversion. Choice C (1 liter) is incorrect because it is the equivalent value in liters, not the conversion factor. Choice D (10 liters) is incorrect as it is not the correct conversion of milliliters to liters.

4. Convert 34.5 grams to kilograms (kg).

• A. 3.45 kg
• B. 34.5 kg
• C. 345 kg
• D. 3.45 grams

Correct answer: A

Rationale: To convert grams to kilograms, divide by 1,000 since there are 1,000 grams in a kilogram. Therefore, 34.5 grams ÷ 1,000 = 0.0345 kilograms. The correct answer is 3.45 kg (not 3.45 grams, which is the amount given in the initial question). Choices B and C are incorrect as they do not involve the conversion from grams to kilograms. Choice D is also incorrect as it presents the value in grams instead of kilograms.

5. How many milliliters are in 1 liter?

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

Correct answer: C

Rationale: The correct answer is 1,000 milliliters in 1 liter. The conversion from liters to milliliters involves multiplying by 1,000 since 1 liter is equivalent to 1,000 milliliters. Choice A, 10 mL, is incorrect as it represents only a fraction of a liter. Choice B, 100 mL, is also incorrect as it is one-tenth of a liter. Choice D, 10,000 mL, is significantly larger than the correct answer and represents 10 liters, not 1 liter.
