Convert Metre to Kilometre
1 metre = 0.001 kilometre (km). For example, 10 metre = 0.01 kilometre and 100 metre = 0.1 kilometre. Type any value below to convert metre to kilometre both ways — it runs entirely in your browser.
Quick answer: Metre to Kilometre
1 Metre = 0.001 Kilometre (m → km). To convert metre to kilometre, multiply by 0.001. To convert kilometre to metre, multiply by 1,000. The converter at the top does this instantly and both ways; the sections below give the formula, worked examples, a full conversion chart and answers to the most common metre-to-kilometre questions.
How to convert Metre to Kilometre
To convert metre to kilometre, multiply the number of metre by the conversion factor 0.001, because 1 m = 0.001 km. The conversion is linear, so the same factor works for any value — whole numbers, decimals or fractions. For the reverse direction, 1 km = 1,000 m, so you divide by 0.001 (or multiply by 1,000) to turn kilometre back into metre.
km = m × 0.001 ·
m = km × 1,000
- Write down the value you want to convert, in metre.
- Multiply it by 0.001.
- The result is the same area/length/quantity expressed in kilometre.

Metre vs Kilometre: which is bigger?
A kilometre is the larger unit: one kilometre equals 1,000 metres. Put another way, you need 1,000 metres to make a single kilometre.
What is a Metre? History, origin and usage
The metre was conceived during the French Revolution: in 1791 the French Academy of Sciences defined it as one ten-millionth of the distance from the North Pole to the Equator along the meridian through Paris. Its name comes from the Greek metron, 'a measure'. It was later embodied in a platinum bar (1799), and in 1960 redefined using the wavelength of krypton-86 light.
The metre is the SI base unit of length and the foundation of the entire metric system used by science and most of the world. Every other unit in this category is defined as a multiple or fraction of it.
Since 1983 the metre has been defined by fixing the speed of light: it is the distance light travels in a vacuum in 1/299,792,458 of a second. This means the metre is no longer tied to any physical artefact and can be reproduced anywhere in the universe.
What is a Kilometre? History, origin and usage
The kilometre combines the Greek-derived prefix 'kilo-' (from khilioi, 'thousand') with the metre. It was among the eight original decimal prefixes adopted by the French Academy of Sciences in 1795, soon after the metre itself was defined during the French Revolution.
The kilometre is the standard unit for road, map and geographic distances throughout most of the world. Nearly every country signs its highways and speed limits in kilometres; the main holdouts that still post road distances in miles are the United States and the United Kingdom.
Although the prefix 'kilo-' comes from Greek, the names of the metric submultiples such as deci- and centi- were drawn from Latin instead. The popular running benchmark known as a '5K' is simply a five-kilometre race.

Tips for converting Metre to Kilometre
- To go from metre to kilometre, multiply by 0.001; to go back, divide by 0.001 (or multiply by 1,000).
- For a quick mental estimate, remember that 1 metre ≈ 0.001 kilometre, so 10 metre ≈ 0.01 kilometre.
- The converter above keeps full precision; the tables round for readability, so use the tool for exact figures.
- Both fields update live as you type — change either side to convert in that direction.
How to use this Metre to Kilometre converter
Type a number into the Metre field and the equivalent in Kilometre appears instantly — there is no “convert” button to press and nothing is sent to a server, so it works offline once the page has loaded and is safe for any data. You can also type into the Kilometre field to convert the other way (kilometre to metre). Use the swap control to flip the two units, and copy the result with a single click. Because the calculation runs in your browser with full floating-point precision, the converter is more exact than the rounded figures shown in the reference chart above — use the chart for quick look-ups and the tool for precise work.
Accuracy and method
Every figure on this page — the formula, the worked examples, the conversion chart and the “convert to other units” tables — is computed from a single verified conversion factor (1 m = 0.001 km), never copied from a hand-typed lookup table that could drift. That factor is derived from each unit’s definition in terms of a common base unit, and an automated check re-verifies all of the site’s factors on every update, so the numbers here stay correct over time. This matters for metre-to-kilometre conversions because a small rounding error in a published table compounds quickly at larger quantities; computing from the exact factor avoids that.
Sources
- BIPM — The International System of Units (SI Brochure) — the defining document for the SI, published by the International Bureau of Weights and Measures. It fixes the base unit that this conversion resolves to, which is why the factor here can be exact rather than approximate.
- NIST — Definitions of the SI base units — the US National Institute of Standards and Technology reference for the SI base units, used here as an independent cross-check on the base-unit definition.
The metric units (km, m, cm, mm, µm) are exact by definition, and the imperial units (mile, yard, foot, inch, nautical mile) use their exact international values. Traditional units (hand, span, finger, cubit, rod/pole, link, rope, ken, league) are given at their commonly accepted standard sizes — historical local values sometimes differed, so confirm against a primary source before relying on them for legal or historical work.
Frequently asked questions
- How many kilometre are in 1 metre?
- 1 metre = 0.001 kilometre (km). To convert any number of metre to kilometre, multiply by 0.001.
- How do I convert metre to kilometre?
- Multiply the number of metre by 0.001. For example, 10 metre = 10 × 0.001 = 0.01 kilometre, and 25 metre = 0.025 kilometre.
- How many metre are in 1 kilometre?
- 1 kilometre = 1,000 metre. So to convert kilometre back to metre, multiply by 1,000.
- What is the formula to convert metre to kilometre?
- kilometre = metre × 0.001. The reverse formula is metre = kilometre × 1,000.
- How much is 100 metre in kilometre?
- 100 metre = 0.1 kilometre. (And 1000 metre = 1 kilometre.)
- Which is bigger, a metre or a kilometre?
- A kilometre is larger: 1 kilometre = 1,000 metre.
- Is this metre to kilometre converter accurate?
- Yes — every value is computed from the exact 0.001 km per m factor (not rounded look-up tables), and the factors are re-verified automatically on every update.
- Can I convert kilometre to metre too?
- Yes. The converter works both ways — enter a value in either field. 1 kilometre = 1,000 metre.
