Is 200 m greater than 20000 mm?

Answer 1

Yes.

1 meter = 1000 millimeters (mm), so 200 meters = 200,000 millimeters.

Convert them to the same units and then the comparison can be made.

1 m = 1000 mm

⇒ 20000 mm = 20000 ÷ 1000 m = 20 m

200 m is greater than 20 m, so 200 m is greater than 20000 mm.
