How do you convert 1.49 m into millimeters?
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
