How to Convert Nanometer to Centimeter
- 1 nm = 1 × 10⁻⁷ cm
- 1 cm = 10000000 nm
- Example: convert 15 nm to cm: 15 nm = 15 × 1 × 10⁻⁷ cm = 0.0000015 cm
Formula
cm = nm ÷ 10000000
Derivation from SI units:
- 1 nm = 10⁻⁹ m
- 1 cm = 10⁻² m
- 1 nm = 1 × 10⁻⁹ m ÷ 0.01 m per cm = 1 × 10⁻⁷ cm
Both units are defined exactly, so the factor is exact. Nanometer definition: nanometer; Centimeter definition: centimeter.
Worked examples
- A reading of 20 nm converts to 0.000002 cm.
20 nm × 1 × 10⁻⁷ = 0.000002 cm - A value of 500 nm is 0.00005 cm.
500 nm × 1 × 10⁻⁷ = 0.00005 cm

Where it's used
Nanometers are used for wavelengths of light (UV, visible, near-IR), while centimeters appear in body height (e.g. 175 cm). Both measure length and distance, so the conversion is a fixed factor.

Frequently asked questions
How many centimeters are in 1 nanometer?
1 nm = 1 × 10⁻⁷ cm.
How do I convert nanometers to centimeters?
Multiply the value in nm by 1 × 10⁻⁷, or divide it by 10000000. For example, 15 nm × 1 × 10⁻⁷ = 0.0000015 cm.
Is the nm to cm conversion exact?
Yes. Both units are defined exactly, and 1 nm is exactly 1 × 10⁻⁷ cm.
