nm to cm Converter - Nanometer to Centimeter

Nanometer (nm) to Centimeter (cm)

Direct answer

1 nm = 1e-7 cm

cm = nm × 1e-7

Converter

Input

Result

1e-7cm

cm = nm × 1e-7

nm = cm × 10,000,000

Example: 10 nm = 10 × 1e-7 = 0.000001 cm.

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

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

1 nm = 1e-7 cm.

10 nm = 0.000001 cm.

100 nm = 0.00001 cm.

Use cm = nm × 1e-7.

1 cm = 10,000,000 nm.

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