Hint: Take the basic reference of conversion of meters to centimetres i.e. 1m=100cm . For 18 meters, multiply both the sides by 18 to get the required conversion. Then check the units of both the sides.

Complete step by step answer:
There are two types of systems of Units. They are MKS (meter- kilogram-second) and CGS (centimetre-gram-second).
Meters: Meter is the fundamental unit of length in MKS or SI (International system of units). It is defined as the length of the path travelled by light in vacuum during a time interval of 1299792458 of a second which can be denoted by ‘m’.
Centimetres: Centimetre is the base unit in the CGS system. It is used in measuring length for many everyday measurements. A centimetre is equal to 0.01 meter which can be denoted by ‘cm’.
Coming to the conversion part
We know, 1cm=0.01m
Multiplying both the sides by 100, we get
1cm×100=0.01m×100100cm=1m
We can write it as
1m=100cm
Since we required to convert 18 meters to centimetres
Hence multiplying both the sides by 18, we get
1m×18=100cm×1818m=1800cm
This is the required conversion.

Note:
Conversion should be done according to the proper unit conversion of meter to centimetre. In general the basic unit for reference is 1m=100cm . After conversion the units on both sides should remain the same. Meters and centimetres are the basic units of length that are used in our day to day life widely.
