cm to nm Converter - Centimeter to Nanometer

Centimeter (cm) to Nanometer (nm)

Direct answer

1 cm = 10,000,000 nm

nm = cm × 10,000,000

Converter

Input

Result

10,000,000nm

nm = cm × 10,000,000

cm = nm × 1e-7

Example: 10 cm = 10 × 10,000,000 = 100,000,000 nm.

Express both cm and nm in the same base unit m (meter), then cancel the shared base unit.

1
Rewrite cm in the base unit
$1 cm = 0.01 m$
2
Rewrite nm in the base unit
$1 nm = 1 \times 1 0^{- 9} m$
3
Forward conversion
$1 cm = \frac{0.01 m}{1 \times 1 0 ^{- 9} m} \times 1 nm = \frac{0.01}{1 \times 1 0 ^{- 9}} nm = 10, 000, 000 nm$
4
Reverse conversion
$1 nm = \frac{1 \times 1 0 ^{- 9} m}{0.01 m} \times 1 cm = \frac{1 \times 1 0 ^{- 9}}{0.01} cm = 1 \times 1 0^{- 7} cm$

1 cm = 10,000,000 nm.

10 cm = 100,000,000 nm.

100 cm = 1,000,000,000 nm.

Use nm = cm × 10,000,000.

1 nm = 1e-7 cm.

Use the conversion factor and round the result to the precision required by your calculation.
