Unit

Visual Magnitude Ratio 1 m = 0.001 km

1 Meter 100%

0.001 Kilometer 0.1%

1 meter = 0.001 kilometer High precision

How the math works

Formula guide

1 × (1 ÷ 1000) = 0.001

Both units are measured against the same base. A kilometer is 1000 times larger than a meter, so 1 meter becomes 0.001 kilometer.
