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
