Question

How do you convert $345$cm to meters$?$

Answer 1

We have to know what is cm and what is meters. Here cm is called centimetre. This is a unit of length. There are hundreds of centimetres in one meter. This is a unit of distance or displacement also in the metric system. This cm is the base unit in the CGS system. A cm is equivalent to the width of the fingernail of an average adult person. Meter is also the unit of length. In the MKS system.

Complete answer:
The word centi means one hundred. Now, cm is equal to $\dfrac{1}{{100}}$th of a meter.
That means $100$ cm is equal to one meter.
So, here we have $345$ cm which is equal to $345/100$ meters and it means $3.45$ meters.

Additional information:
Meter is the fundamental unit of length in S.I. unit. This meter is the length of the path travelled by light in a vacuum medium with a time interval of $\dfrac{1}{{299}},729,458$ of a second. One centimetre is equal to $0.03281$ feet. Foot is also a unit of length. One foot is equal to twelve inches.

Note: We have to know everything about meters and centimetres, then only we can give correct answers related to this question. Students should know that one meter is equal to one thousand millimetres. And one cm is equal to ten millimetres. Which means one millimetre is equal to ten to the power minus three meters. ${10^{ - 3}}m = 1mm$ . And also, one centimetre is equal to ten to the power minus two meters. ${10^{ - 2}}m = 1cm$.
