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 10 ^{10} 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 nm~~cm~~

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
