There are 1*[tex]10^{18}[/tex] nanometers in 1 gigameters.
Given that there is 1 gigameters.
We are required to tell how many nanometers are there in 1 gigameters. Basically we have to convert 1 gigameters into nanometers.
The gigametre (Gm) is basically a unit of length in the International System of Units, defined as [tex]10^{9}[/tex] metres using the SI prefix system.
1 gigameter=[tex]10^{9}[/tex] meters
1 meters=1 gigameters/[tex]10^{9}[/tex]----------1
A nanometer is basically a unit of spatial measurement that is [tex]10^{-9}[/tex] meters.
1 nanometers=[tex]10^{-9}[/tex] meters
1 meters=1 nanometers/[tex]10^{-9}[/tex]--------2
From 1 &2
1gigameters/[tex]10^{9}[/tex]=1nanometers/[tex]10^{-9}[/tex]
1gigameters=[tex]10^{9}[/tex]/[tex]10^{-9}[/tex] nanometers
1 gigameters=[tex]10^{9+9}[/tex] nanometers
1 gigameters=[tex]10^{18}[/tex] nanometers
Hence there are 1*[tex]10^{18}[/tex] nanometers in 1 gigameters.
