Express 3 meters in millimeter

Answer 1

There are 1,000 millimetres in a metre. So to convert from metres to millimetres you have to multiply by 1,000. In this case we have 3 metres so do:

3 x 1,000 = 3,000

And thus 3 metres is 3,000 millimetres.

1 mm = 1000micro meters

so 2.5 mm = 2500 micrometers

Answer 3

1 m=1000 mm

3 m=3000 mm
