    How to Convert Centimeter to Nanometer

    • 1 cm = 10000000 nm
    • 1 nm = 1 × 10⁻⁷ cm
    • Example: convert 15 cm to nm: 15 cm = 15 × 10000000 nm = 150000000 nm

    Formula

    nm = cm × 10000000

    Derivation from SI units:

    • 1 cm = 10⁻² m
    • 1 nm = 10⁻⁹ m
    • 1 cm = 0.01 m ÷ 1 × 10⁻⁹ m per nm = 10000000 nm

    Both units are defined exactly, so the factor is exact. Centimeter definition: centimeter; Nanometer definition: nanometer.

    Worked examples

    1. A reading of 30 cm converts to 300000000 nm.
      30 cm × 10000000 = 300000000 nm
    2. A value of 150 cm is 1500000000 nm.
      150 cm × 10000000 = 1500000000 nm

    Where it's used

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