Out of the 3 that were listed, the "conversion" that is invalid is 1 meter = 10 millimeters.
Step-by-step explanation:
First: Well, for something like this, you don't really need steps, you just need to know how to do process of elimination and also your conversions:
We know that 1 meter is 100 centimeters
We know 1 kilometer is 1000 meters
We know that 1 meter is 10 millim....... Wait. Do we know that?
No! 1 meter is not 10 millimeters, it's 1000 millimeters. So 1 meter = 10 millimeters is invalid.
