nm to mm Converter - Nanometer to Millimeter

Nanometer (nm) to Millimeter (mm)

Direct answer

1 nm = 0.000001 mm

mm = nm × 0.000001

Converter

Input

Result

0.000001mm

mm = nm × 0.000001

nm = mm × 1,000,000

Example: 10 nm = 10 × 0.000001 = 0.00001 mm.

Express both nm and mm 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 mm in the base unit
$1 mm = 0.001 m$
3
Forward conversion
$1 nm = \frac{1 \times 1 0 ^{- 9} m}{0.001 m} \times 1 mm = \frac{1 \times 1 0 ^{- 9}}{0.001} mm = 0.000001 mm$
4
Reverse conversion
$1 mm = \frac{0.001 m}{1 \times 1 0 ^{- 9} m} \times 1 nm = \frac{0.001}{1 \times 1 0 ^{- 9}} nm = 1, 000, 000 nm$

1 nm = 0.000001 mm.

10 nm = 0.00001 mm.

100 nm = 0.0001 mm.

Use mm = nm × 0.000001.

1 mm = 1,000,000 nm.

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