multiply by 10
10
210 cm = 2100 mm
cm
multiply by 101 centimeter (cm) is 10 millimeters (mm)So, if you have a 40 cm long rope, you can also say it is 400 mm long.
10 mm = 1 cm so 897 mm = 897/10 = 89.7 cm. Simple.
634 mm.
30 mm Is The Largest
mm divided by 10 = cm
If you convert all the measurements to the same unit you have:2.5 cm, 20.1 cm, 19.2 cm, 20.3 cm; OR25 mm, 201 mm, 192 mm, 203 mmFrom these you can then clearly see that the longest measurement is then 20.3 cm (which is 203 mm if converted).
It depends on what measurement you chose it could be in cm which would be 200 cm and in mm it would be 2,000 mm.
97.5 mm
They are both units to make a linear measurement. They are both metric units. MM are smaller than CM
