Which of the following is not equal to 0.1 centimeters? 0.000001 kilometers (km) 0.001 meters (m) 10 millimeters (mm) 1000 micrometers (µm)

Which of the following given measurement are not equal to 0.1 centimeters:

first choice = 0.000001 kilometers

=> 0.1 cm = 1e-6 km

Second choice = 0.001 meters

=> 0.1 cm = 0.001 meters

third choice = 10 millimeters

=> 0.1 cm = 1 millimeter

Fourth choice = 1000 micrometer

=> 0.1 cm = 1 000 micrometer

Thus the not equal that we are looking for is the millimeter. Because 0.1 centimeter is equals to 1 millimeter and not 10.
