Kilometer (km) to Meter (m)

Direct answer

1 km = 1,000 m

m = km × 1,000

Converter

Input

Result

1,000m

m = km × 1,000

km = m × 0.001

Example: 10 km = 10 × 1,000 = 10,000 m.

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

1
Rewrite km in the base unit
$1 km = 1, 000 m$
2
Rewrite m in the base unit
$1 m = 1 m$
3
Forward conversion
$1 km = \frac{1 , 000 m}{1 m} \times 1 m = \frac{1 , 000}{1} m = 1, 000 m$
4
Reverse conversion
$1 m = \frac{1 m}{1 , 000 m} \times 1 km = \frac{1}{1 , 000} km = 0.001 km$

1 km = 1,000 m.

10 km = 10,000 m.

100 km = 100,000 m.

Use m = km × 1,000.

1 m = 0.001 km.

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