1. How many millimeters (mm) are in 3.45 meters?

• A. 345 mm
• B. 3,450 mm
• C. 345,000 mm
• D. 3.45 mm

Correct answer: B

Rationale: To convert meters to millimeters, you need to multiply by 1,000 because there are 1,000 millimeters in a meter. Therefore, 3.45 meters × 1,000 = 3,450 millimeters. Choices A, C, and D are incorrect because they do not reflect the correct conversion factor from meters to millimeters.

2. Convert 0.5 liters to milliliters.

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

Correct answer: B

Rationale: To convert liters to milliliters, you need to multiply by 1000 as there are 1000 milliliters in 1 liter. Therefore, when converting 0.5 liters to milliliters, the correct answer is 0.5 x 1000 = 500 ml. Choice A (50 ml) is incorrect because it represents the conversion of 0.05 liters, not 0.5 liters. Choice C (5 ml) is incorrect as it represents the conversion of 0.005 liters. Choice D (0.5 ml) is incorrect as it does not reflect the correct conversion from liters to milliliters.

3. How many ounces is equal to 1 gram?

• A. 0.015 ounces
• B. 0.035 ounces
• C. 0.045 ounces
• D. 0.055 ounces

Correct answer: B

Rationale: To convert grams to ounces, you need to multiply the weight in grams by 0.035 to get the equivalent weight in ounces. Therefore, 1 gram is equal to 0.035 ounces. Choices A, C, and D are incorrect conversions and do not accurately represent the conversion factor from grams to ounces.

4. What is 0.25 mg to mcg?

• A. 250 mcg
• B. 25 mcg
• C. 2.5 mcg
• D. 2500 mcg

Correct answer: A

Rationale: To convert milligrams (mg) to micrograms (mcg), you multiply by 1000 because 1 mg is equal to 1000 mcg. Therefore, 0.25 mg is equal to 250 mcg. Choices B, C, and D are incorrect as they do not consider the correct conversion factor.

5. What is 0.04 liters converted to milliliters?

• A. 40 ml
• B. 4 ml
• C. 400 ml
• D. 0.4 ml

Correct answer: A

Rationale: To convert liters to milliliters, you need to multiply by 1,000 since there are 1,000 milliliters in a liter. So, to convert 0.04 liters to milliliters, you would multiply 0.04 by 1,000, giving you 40 milliliters. This means that choice A, '40 ml', is the correct answer. Choices B, C, and D are incorrect because they do not correctly convert liters to milliliters. Choice B, '4 ml', is incorrect as it is 10 times smaller than the correct conversion. Choice C, '400 ml', is incorrect as it is 10 times larger than the correct conversion. Choice D, '0.4 ml', is incorrect as it is one-tenth of the correct conversion.
