1. What is the equivalent of 255.0 pounds in kilograms (1 kg = 2.205 lbs)?
- A. 115.7 kg
- B. 126.0 kg
- C. 115.8 kg
- D. 115.6 kg
Correct answer: D
Rationale: To convert pounds to kilograms, you need to divide the weight in pounds by 2.205 (1 kg = 2.205 lbs). Therefore, 255.0 pounds divided by 2.205 equals 115.6 kilograms. This results in choice D being the correct answer. Choices A, B, and C are incorrect as they do not reflect the accurate conversion calculation from pounds to kilograms.
2. 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.
3. 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.
4. What does 'km' stand for in the metric system?
- A. kilometer
- B. kilomole
- C. kilobyte
- D. knot
Correct answer: A
Rationale: In the metric system, 'km' stands for kilometer, which is a unit of length equal to 1,000 meters. This choice is correct as 'kilometer' is the standard unit for measuring long distances. Choice B, 'kilomole,' is incorrect as it is a unit in chemistry representing a quantity of substance. Choice C, 'kilobyte,' is incorrect as it is a unit of digital information storage, not a unit of measurement. Choice D, 'knot,' is incorrect as it is a unit of speed used in navigation and aeronautics, not a unit of length in the metric system.
5. What is the equivalent of 3.54 millimeters in meters (m)?
- A. 0.0354 m
- B. 0.00354 m
- C. 35.4 m
- D. 0.035 m
Correct answer: B
Rationale: To convert millimeters to meters, you need to divide by 1,000 since there are 1,000 millimeters in a meter. Therefore, 3.54 mm ÷ 1,000 = 0.00354 meters. Choice A (0.0354 m) is incorrect as it is 10 times the correct conversion. Choice C (35.4 m) is incorrect as it would be the equivalent of 35,400 millimeters. Choice D (0.035 m) is also incorrect as it is 100 times greater than the correct conversion.
