How many millimeters does the metric ruler have?

Answer 1

120
Ruler sizes can vary from 15 to 60 centimeters. Most common rulers are 32cm long, with measures from 0 to 30cm. (30cm ruler, 1 foot). Some fold out rulers can be 120cm, although are rare. Some 30cm rulers can be folded in half to create a doule-thickness 15cm long ruler, but folded out for a 30cm.

Answer 2

It depends on the rule:

A 6" or 15 cm rule will be marked up to 150 mm

A 12", 1 ft or 30 cm rule will be marked up to 300 mm

I have an 18" or 46 cm rule which is marked up to 460 mm.

At my college there are 1m rules which are marked up to 1,000 mm

Tape measures can be obtained that are even longer:

I have a 10 m tape measure marked up to 10,000 mm, and

a 20 m tape but that is only marked at every 2 mm up to 20,000 mm.

Answer 3

The answer to your question would depend on the size of the ruler. For example, on a metric ruler, it measures by centimeters. Between the centimeter marks are the smaller "ticks" between each one. There are 10 millimeters in a centimeter, and there are 100 centimeters in a meter. This would mean that there are 1,000 millimeters in a meter.

Thanks for the question!
