Before you measure something, you need to define WHAT you measure.

Without such a definition a measurement would be nonsense.

E.g. you have a multimeter and read out e.g. '204.5' from the display.

Now such a value makes no sense at all, if you do not say, what this 
value is meant to measure.

In case of 'length' you need to say, what is meant with this word.

Something like 'spatial distance along a straight line' would be part of 
that definition and that these distances can be summed up and these 
partial distances may be infinetesially small.

Something in that realm would be a definition of 'length'.

And once you measure something similar, you need to say, that this 
measurement should be understood as length, even if the line measured is 
not streigth, but e.g the circumference of a circle.
