The formulas for conversion are represented below:
nm = cm * 10000000
Example: 30 Centimeters in Nanometers:
nm = cm * 10000000
nm = 30 * 10000000
nm = 300.000.000
cm = nm / 10000000
Example: 1.5 Nanometers in Centimeters:
cm = nm / 10000000
cm = 1,5 / 10000000
cm = 1,5x10-7
Considering that 1 Centimeter is equivalent to 10,000,000 Nanometers, you can use a rule of three to obtain that 1000 Centimeters are equal to 1010 Nanometers.
>
1 cm - 10.000.000 nm
1000 cm - x
Apply the rule of three and get:
x cm = 10.000.000 x 1.000 nmcm
x = 10.000.000.000 nm
If every 10,000,000 Nanometers we have 1 Centimeter, just divide the number of Nanometers (1000) by 10000000, so you will obtain that 1000 nm equals 0.0001 cm. Observe the calculation below:
cm = nm / 10.000.000
cm = 1000 / 10000000
cm = 0,0001
