Question

what is relationship between meter and nanometer

Answer 1

Nanometre is a very, very small unit of measuring length. It is written as nm.

 

1 nanometre = 1/109 metre

So, 1 nm = 10-9 m

Atomic radius of C = 0.077 nm

So, atomic radius of C in m = 0.077 x 10-9 nm.

Answer 2

$1 \: nanometre\: = \: {10}^{-9} \: metre$
nanometre(nm): It is the one billionth part of a metre.
