Question

An engineer is proof-reading his report and finds that he has mistakenly used micrometers as a unit of measure. His experiment showed a measurement of 2 micrometers, but the government requires the measurement to be in millimeters.

How should the engineer record the measurement (if there are 1000 micrometers in 1 millimeter)?
A) 0.002 mm
B) 2 mm
C) 0.2 mm
D) 2000 mm

Answer 1

To convert 2 micrometers to millimeters, divide 2 by 1000, resulting in a measurement of 0.002 mm.

Step-by-step explanation:

The question requires converting micrometers to millimeters. Since 1 millimeter is equal to 1000 micrometers, to convert 2 micrometers to millimeters we need to divide the number of micrometers by 1000. Thus, the conversion is as follows:

1. Start with the measurement in micrometers (2 μm).
2. Divide the number of micrometers by 1000 to get the measurement in millimeters (2 μm / 1000).
3. This results in 0.002 millimeters.

Therefore, the engineer should record the measurement as 0.002 mm.
