What do the lines of a metric ruler mean?

Answer 1

Different rulers will have different increments, so we can't give a definitive answer - however -

I would expect the ruler to at least mark off the centimeters with larger lines and then probably use smaller lines as millimeter increments. Some rulers could use even smaller increments such as half millimeters but I've never personally seen any rulers that went for tenths of a millimeter. When I need to get to that kind of precision I always opt for a different measuring tool such as a micrometer.

Answer 2

something like texture, color, smell, sound and taste

Answer 3

They are called millimeter lines.

Answer 4

1. thinner side-cm .

Answer 5

It could represent 1 millimetre, 0.1 inch, 1/16 inch or 1/32 inch depending on whether it is a metric or customary ruler and the quality of the graduation.

Answer 6

they mean mili meters, idiot :)
