71 nm is equal to 0.0071 cm.
Here's how to convert nanometers (nm) to centimeters (cm):
1 nanometer (nm) = 1 x 10^-9 meters (m)
1 centimeter (cm) = 1 x 10^-2 meters (m)
Therefore, 1 nm = 1 x 10^-7 cm
To convert 71 nm to cm, multiply by the conversion factor:
71 nm x (1 x 10^-7 cm / 1 nm) = 0.0071 cm
