Question

How do you convert 1.49 m into millimeters?

Answer 1

1490 millimetres

Explanation:

With the measure getting smaller (millimetres are much smaller than metres), the number of measures we need to cover a certain distance will get bigger. Each time we move to the next smaller measure, we move the decimal point to make the number bigger:

From 1.49 metres, we change this to decimetres. A decimetre is 10 times smaller than a metre and so:

1.49 metres = 14.9 decimetres.

And then we move to the next smallest measure, centimetres:

14.9 decimetres = 149 centimetres

And lastly we get to millimetres:

149 centimetres = 1490 millimetres
