1. How many centimeters are in 1 inch?

• 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. Choice D (1 cm) is incorrect as it inaccurately states the conversion value for 1 inch.

2. How many millimeters are in 1 centimeter?

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

Correct answer: B

Rationale: The correct answer is B: '10 mm'. There are 10 millimeters in 1 centimeter. To convert centimeters to millimeters, you multiply by 10 because 1 centimeter is equivalent to 10 millimeters. Choice A '1 mm' is incorrect as it represents the size of 1 millimeter, not the conversion from centimeters to millimeters. Choice C '100 mm' is incorrect as it is the equivalent of 1 meter, not 1 centimeter. Choice D '1,000 mm' is incorrect as it is the equivalent of 1 meter, not 1 centimeter.

3. How many ounces are in 0.5 liters?

• 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 volume in liters by 33.814. In this case, 0.5 liters multiplied by 33.814 equals approximately 16.91 ounces. This conversion is commonly used in culinary and liquid measurements. Choices B, C, and D are incorrect as they do not reflect the correct conversion factor from liters to ounces.

4. What is 0.5 liters converted 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 the number of liters by 1000 because there are 1000 milliliters in 1 liter. Therefore, 0.5 liters converts to 500 milliliters. Choice A (50 ml) is incorrect as it is the result of multiplying by 10 instead of 1000. Choice C (5 ml) is incorrect as it is the result of dividing by 10 instead of multiplying by 1000. Choice D (0.5 ml) is incorrect as it represents the original quantity in milliliters, not the conversion from liters.

5. 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.
