1. How many centimeters are in 0.25 meters?

• A. 2.5 cm
• B. 25 cm
• C. 250 cm
• D. 0.25 cm

Correct answer: B

Rationale: To convert meters to centimeters, you need to multiply by 100 since there are 100 centimeters in a meter. Therefore, 0.25 meters x 100 = 25 centimeters. Choice A, '2.5 cm,' is incorrect as it is the result of multiplying by 10 instead of 100. Choice C, '250 cm,' is incorrect as it is the result of multiplying by 1000. Choice D, '0.25 cm,' is incorrect as it suggests the conversion is in the opposite direction, from centimeters to meters.

2. What is 0.5 liters in milliliters?

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

Correct answer: B

Rationale: 0.5 liters is equivalent to 500 milliliters. To convert liters to milliliters, you multiply by 1000 since 1 liter equals 1000 milliliters. Therefore, the correct answer is 500 ml (0.5 * 1000 = 500). Choices A, C, and D are incorrect because they do not correctly convert 0.5 liters to milliliters.

3. The metric prefix of Tera is abbreviated as T- and has a value of 10^12. What does Tera mean numerically?

• A. 10^6
• B. 10^9
• C. 10^12
• D. 10^3

Correct answer: C

Rationale: The correct answer is C: 10^12. Tera represents a numerical value of 10^12, which is equivalent to one trillion. It is commonly used in computing and other fields to denote large-scale measurements. Choice A, 10^6, is incorrect as it corresponds to the metric prefix 'Mega.' Choice B, 10^9, is incorrect and corresponds to the metric prefix 'Giga.' Choice D, 10^3, is incorrect and corresponds to the metric prefix 'Kilo.' Therefore, the correct interpretation of the metric prefix Tera is 10^12.

4. What does 'g' stand for in the metric system?

• A. gram
• B. grain
• C. goose
• D. grammage

Correct answer: A

Rationale: In the metric system, 'g' stands for gram, which is the base unit for mass. Choice B, 'grain,' is a measurement unit in the imperial system and not the metric system. Choice C, 'goose,' is unrelated to the metric system. Choice D, 'grammage,' is a term used to describe the weight of paper or fabric, not a unit in the metric system.

5. How many kilometers (km) is equivalent to 1,000 meters?

• A. 0.1 km
• B. 1 km
• C. 10 km
• D. 0.01 km

Correct answer: B

Rationale: To convert meters to kilometers, the conversion factor is 1 kilometer = 1,000 meters. Therefore, to find how many kilometers are in 1,000 meters, you divide 1,000 by 1,000, which equals 1 kilometer. Choice A (0.1 km), Choice C (10 km), and Choice D (0.01 km) are incorrect because they do not correctly represent the conversion of 1,000 meters to kilometers.
