• A. 2.54 cm
• B. 3 cm
• C. 2 cm
• D. 1 cm

Correct answer: A

Rationale: The correct answer is A: 2.54 cm. One inch is equivalent to 2.54 centimeters. This conversion factor is commonly used when converting measurements between the metric and imperial systems. Choice B (3 cm) is incorrect as it is not the accurate conversion factor for 1 inch. Choice C (2 cm) is also incorrect as it does not reflect the correct conversion.

2. What is 0.4 grams in milligrams?

• A. 400 mg
• B. 40 mg
• C. 4 mg
• D. 4000 mg

Correct answer: A

Rationale: To convert grams to milligrams, you need to multiply by 1000 as there are 1000 milligrams in one gram. Therefore, 0.4 grams x 1000 = 400 mg. Choice A, 400 mg, is the correct answer. Choices B, C, and D are incorrect because they do not correctly apply the conversion factor of 1000 to convert grams to milligrams.

3. 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.

4. How many milliliters are in 1.5 liters?

• A. 15 mL
• B. 1,500 mL

• D. 150,000 mL

Correct answer: B

Rationale: To convert liters to milliliters, you need to multiply by 1,000 since there are 1,000 milliliters in a liter. Therefore, 1.5 liters x 1,000 = 1,500 milliliters. Choice A, 15 mL, is incorrect as it represents the conversion of 0.015 liters. Choice C, 150 mL, is incorrect as it represents the conversion of 0.15 liters. Choice D, 150,000 mL, is incorrect as it represents the conversion of 150 liters.

5. How many pints are in one quart?

• A. 1 pint
• B. 2 pints

Choice C, 3 pints, and Choice D, 4 pints, are also incorrect as they do not accurately represent the conversion of quarts to pints.
