Which of the following is not a valid conversion factor?

1 meter/100 centimeters

1mL/1 cm3

1 kilometer/1000 Meters

1 meter/10 millimeters

1 meter/10 millimeters is not a valid conversion factor.

Step-by-step explanation:

Because 10 millimeters (mm) is  = to 1 centimeter (cm). This answer is obviously the only logical explanation. Contributing to the fact that  1 meter is equal to 100 centimeters and dividing that by 10 would make it 0.1 meters = 10 centimeters and 0.1 Meters =  100 Millimeters so that is clearly wrong that is why 1 meter/ 10 millimeters is not a valid conversion factor.
