Question

How many meters is one nanometer?

Answer 1

Convert meter into nanometer:

The prefix "nano" stands for $\times {10}^{-9}$.

Implying that, we have to multiply $1$ meter by ${10}^{-9}$ to convert from meter to nanometer.

Thus,

$1$ nanometer $=1\times {10}^{-9}\mathrm{m}$

$\Rightarrow$ $1$ nanometer $=0.000000001\mathrm{m}$

Therefore, $1$ nanometer$=0.000000001$ meter.
