About Centimeter
The centimeter is a metric unit equal to one hundredth of a meter (0.01 m). It is convenient for everyday objects, paper sizes, and body measurements.
About Nanometer
The nanometer is one billionth of a meter. It describes wavelengths of light, semiconductor features, and molecular scales.
How to convert centimeters to nanometers
1 centimeter is equal to 1.00000000e+7 nanometer:
1 cm = (0.01 m ÷ 1e-9 m) nm = 1.00000000e+7 nm
Each centimeter is defined as 0.01 m and each nanometer as 1e-9 m, so one cm equals 0.01 ÷ 1e-9 nm = 1.00000000e+7 nm.
Let d(cm) be the numeric value of the same length measured in Centimeter (cm), and d(nm) the value in Nanometer (nm). Then:
d(nm) = d(cm) × (0.01 / 1e-9)
Equivalently, divide by how many cm fit into one nm (meters per nm divided by meters per cm):
d(nm) = d(cm) ÷ 1.00000000e-7
Or: nanometer = centimeter ÷ 1.00000000e-7
Examples
Example #1: Convert 20 cm to nanometer
20 cm = 20 cm × (0.01/1e-9) nm = 200000000 nm
20 cm = 20 cm ÷ 1.00000000e-7 = 200000000 nm
Example #2: Convert 50 cm to nanometer
50 cm = 50 cm × (0.01/1e-9) nm = 500000000 nm
50 cm = 50 cm ÷ 1.00000000e-7 = 500000000 nm
Summary
To convert Centimeter to Nanometer, multiply the value in cm by the ratio of meters per cm divided by meters per nm. Equivalently: value_nm = value_cm × (0.01 / 1e-9). Numerically, 1 cm equals 10000000 nm.
Relationship context
Both units are metric (SI) and tied to the meter. Converting between them uses powers of ten (or simple rational factors), so the relationship is exact in decimal arithmetic. The factor from Centimeter to Nanometer is 1.000000e+7 (1 cm = 10000000 nm).
