To measure milli- from the base unit, the decimal point moves how many places?

Explanation:
Milli- means one thousandth of a unit, so moving from the base unit to the milli-unit makes the value larger by a factor of 1000. That requires shifting the decimal three places to the right. For example, 1 meter equals 1000 millimeters, 0.5 meters equals 500 millimeters, and 0.012 meters equals 12 millimeters. If you ever convert the other way, from milli to base, you’d move the decimal three places to the left. So the decimal point moves three places to the right.
