Answer:
There are 1000 millimeters in a meter.
Starting from lower scale that is, centimeter, decimeter and then meter
1 cm = 10 mm
1 dm = 10 cm
And 1 meter = 10 dm
So, when you go up to mm from meter, we will do [tex]10^{3}[/tex] to get the relation between meter and mm.
Hence, 1 meter = [tex]10\times10\times10=1000[/tex] millimeters.
