Meter (m)

The meter (m) is the SI base unit of length and the international standard used worldwide.

Origin
Originally defined as one ten-millionth of the distance from the equator to the North Pole, it is now defined by the distance light travels in vacuum in 1/299,792,458 of a second.
Where it is used
Used for building grids, floor levels, spans, site dimensions and virtually all scientific and engineering work.
Relation to SI
The meter is the SI base unit; every other length unit here is defined from it.

Kilometer (km)

The kilometer (km) equals one thousand meters and measures geographic distance.

Origin
A decimal multiple of the SI meter.
Where it is used
Used for infrastructure alignment, transport planning, site context and mapping distances.
Relation to SI
1 km = 1,000 m exactly.

Frequently asked questions

How many kilometers are in one meter?

1 m equals 0.001 km.

How do I convert meters to kilometers?

Multiply the value by 0.001. For example, 10 m equals 0.01 km.

How do I convert back from kilometers to meters?

1 km equals 1,000 m. The converter above works in both directions, so you can type into either field.

Should I work in millimeters or meters on drawings?

Most architectural and structural drawings outside the US are dimensioned in millimeters to avoid decimal points, while site levels, grids and areas are stated in meters.

Are the imperial values here exact?

Yes. The inch has been defined as exactly 25.4 mm since 1959, so foot, yard and mile conversions are exact rather than rounded.

Is this length converter free to use?

Yes. Every unit conversion runs in your browser, needs no account and is free for professional use.
