# How many nanometers are there in 1 cm?

Sep 20, 2016

$1$ centimeter has $10 , 000 , 000$ i.e. $10$ million nanometers.

#### Explanation:

Standard unit in this system is $1$ meter.

There are a billion i.e. $1 , 000 , 000 , 000$ nano units in a standard unit and hence $1 , 000 , 000 , 000$ nanometers in one meter.

As there are $100$ centimeters in each meter,

$1$ centimeter has $\frac{1 , 000 , 000 , 000}{100} = 10 , 000 , 000$ i.e. $10$ million nanometers.
