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.
