1 meter = 100 centimeter

1 meter = 1000 millimeter

therefore, 100 centimeter = 1000 millimeter

>>> 1 centimeter = 1000/100 millimeter

>>> 1 centimeter = 10 millimeter

1 meter = 1000 millimeter

therefore, 100 centimeter = 1000 millimeter

>>> 1 centimeter = 1000/100 millimeter

>>> 1 centimeter = 10 millimeter
