nm to km Converter - Nanometer to Kilometer

Nanometer (nm) to Kilometer (km)

Direct answer

1 nm = 1e-12 km

km = nm × 1e-12

Converter

Input

Result

1e-12km

km = nm × 1e-12

nm = km × 1e+12

Example: 10 nm = 10 × 1e-12 = 1e-11 km.

Express both nm and km 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 km in the base unit
$1 km = 1, 000 m$
3
Forward conversion
$1 nm = \frac{1 \times 1 0 ^{- 9} m}{1 , 000 m} \times 1 km = \frac{1 \times 1 0 ^{- 9}}{1 , 000} km = 1 \times 1 0^{- 12} km$
4
Reverse conversion
$1 km = \frac{1 , 000 m}{1 \times 1 0 ^{- 9} m} \times 1 nm = \frac{1 , 000}{1 \times 1 0 ^{- 9}} nm = 1 \times 1 0^{12} nm$

1 nm = 1e-12 km.

10 nm = 1e-11 km.

100 nm = 1e-10 km.

Use km = nm × 1e-12.

1 km = 1e+12 nm.

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