Question

How many nanometers are there in $1cm$ $?$

Answer 1

Compute the required value.

Since, there are ${10}^9$ nanometers in one meter and $100cm$ in one meter.

So, the number of nanometers in $1cm$ can be given by:

$\frac{{10}^9}{100}={10}^7$.

Hence, there are ${10}^7$ nanometers in $1cm$.
