1. What is 0.1 liter converted to milliliters?

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

Correct answer: B

Rationale: To convert 0.1 liter to milliliters, you need to multiply by 1000 because there are 1000 milliliters in a liter. Therefore, 0.1 liter converts to 100 milliliters. Choice A (10 ml) is incorrect as it represents 0.01 liters, not 0.1 liters. Choice C (1000 ml) is incorrect as it represents 1 liter, not 0.1 liters. Choice D (1 ml) is incorrect as it is too small a quantity for 0.1 liters.

2. What does the prefix 'centi' mean?

• A. 0.1
• B. 0.01
• C. 0.001
• D. 1

Correct answer: B

Rationale: The prefix 'centi' means 0.01, which is one-hundredth of the base unit. For example, 1 centimeter is equal to 0.01 meters. Choice A (0.1) is incorrect as it represents 'deci,' which means one-tenth. Choice C (0.001) is incorrect as it represents 'milli,' which means one-thousandth. Choice D (1) is incorrect as it is not a valid interpretation of the prefix 'centi.' Therefore, the correct answer is B.

3. What does 'mg' stand for in the metric system?

• A. microgram
• B. milligram
• C. gigabyte
• D. megagram

Correct answer: B

Rationale: 'mg' stands for milligram, which is equal to 1/1,000th of a gram. In the metric system, 'microgram' (choice A) is represented by 'mcg', 'gigabyte' (choice C) is a unit of digital information storage, and 'megagram' (choice D) is equivalent to a metric ton.

4. How many milliliters are in 1 ounce?

• A. 20 ml
• B. 30 ml
• C. 40 ml
• D. 50 ml

Correct answer: B

Rationale: The correct answer is B: 30 ml. 1 ounce is equivalent to 30 milliliters. This conversion is a common one in many contexts involving liquid measurements. Choice A (20 ml), Choice C (40 ml), and Choice D (50 ml) are incorrect conversions and do not represent the accurate conversion between ounces and milliliters.

5. How many grams are in 1 kilogram?

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

Correct answer: C

Rationale: The correct answer is C: 1,000 grams. The metric system follows a logical conversion where 1 kilogram is equal to 1,000 grams. This conversion is a fundamental concept in understanding units of measurement. Choices A, B, and D are incorrect because they do not accurately reflect the conversion between kilograms and grams. Option A (10 grams) is incorrect as it represents 1/100th of the correct conversion. Option B (100 grams) is also incorrect as it represents 1/10th of the correct conversion. Option D (10,000 grams) is significantly higher than the actual conversion, making it incorrect. Understanding these basic unit conversions is essential for various fields where precise measurements are necessary.
