The question, as stated, cannot be answered sensibly. A millilitre is a measure of volume, with dimensions [L3]. A metre is a measure of distance, with dimensions [L]. The two measure different things and elementary dimensional analysis teaches that you cannot convert between measures with different dimensions such as these without additional information.

12,000 millimeters.
3 centiliters = 30 milliliters
You cannot convert in this way. Milliliters is a measure of liquid volume, and meters are a measure of distance. Perhaps you want to know how many milliMETERS are in a meter? If so - see related questions below.
3 hl = 300 liters = 300 000 milliliters
Milliliters (cc's) can't be converted to meters. Milliliters measure volume, while meters measure length.

1.8 meters
46,500
there are 6000 i think!
.00123 millimeters
Millimetres! and the answer is 2,000mm
12,000 millimeters.
3 centiliters = 30 milliliters
multiply by 1000 = 2000 mm
