1. What is 1500 milliliters in liters?

• A. 1.5 liters
• B. 0.15 liters
• C. 15 liters
• D. 0.015 liters

Correct answer: A

Rationale: To convert milliliters to liters, you need to divide by 1000 since there are 1000 milliliters in 1 liter. Therefore, 1500 milliliters divided by 1000 equals 1.5 liters, making option A the correct answer. Option B, 0.15 liters, is incorrect as it would be the conversion of 150 milliliters. Option C, 15 liters, is incorrect because it would be the conversion of 15,000 milliliters. Option D, 0.015 liters, is incorrect as it would be the conversion of 15 milliliters.

2. What is 0.5 liter in ounces?

• A. 16.91 oz
• B. 15.91 oz
• C. 17.91 oz
• D. 18.91 oz

Correct answer: A

Rationale: To convert liters to ounces, you need to multiply the liter value by 33.814. Therefore, to convert 0.5 liters to ounces, you would calculate 0.5 x 33.814 = 16.91 ounces. This conversion factor is commonly used in cooking and liquid measurements. Choice B, C, and D are incorrect as they do not reflect the accurate conversion from liters to ounces.

3. What is 0.2 liters when converted to milliliters?

• A. 20 ml
• B. 200 ml
• C. 2 ml
• D. 2000 ml

Correct answer: B

Rationale: To convert liters to milliliters, you need to multiply by 1000, not 10000. Therefore, 0.2 liters equals 200 ml (0.2 x 1000 = 200 ml). Choice A, 20 ml, is incorrect because it's the result of multiplying by 10 instead of 1000. Choice C, 2 ml, is incorrect as it's the result of ignoring the decimal point. Choice D, 2000 ml, is incorrect because it's the result of multiplying by 10000.

4. How many feet are in one mile?

• A. 5000 feet
• B. 5280 feet
• C. 5300 feet
• D. 5500 feet

Correct answer: B

Rationale: The correct answer is B: 5280 feet. One mile is equivalent to 5280 feet. This is a standard conversion that is widely known. Choice A (5000 feet) is incorrect as it is not the exact conversion of a mile. Choice C (5300 feet) and choice D (5500 feet) are also incorrect as they do not represent the accurate conversion from miles to feet.

5. What is the base unit for mass in the metric system?

• A. milligrams
• B. grams
• C. kilograms
• D. tons

Correct answer: B

Rationale: The base unit for mass in the metric system is grams. Grams are the fundamental unit of mass in the metric system, representing smaller quantities than kilograms and tons. Milligrams are a smaller unit of mass, kilograms are a larger unit, and tons are even larger units. Therefore, the correct choice is grams.
