We have to convert 12.7nm to cm


\\ \sf\longmapsto 12.7nm


\\ \sf\longmapsto 12.7* 10^(-9)m


\\ \sf\longmapsto 0.127* 10^(-7)m


\\ \sf\longmapsto 0.00000127* 10^(-2)


\\ \sf\longmapsto 0.0000013cm

1 meter = 1e9 nm
To get meters, divide nanometers by 1e9: 9.95nm / 1x10^9 = 9.95x10^-9 meters
Answer: 9.95e-9 meters
