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

Kilometre vs Metre: 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 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.
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.

Tips for converting Kilometre to Metre
- To go from kilometre to metre, multiply by 1,000; to go back, divide by 1,000 (or multiply by 0.001).
- For a quick mental estimate, remember that 1 kilometre ≈ 1,000 metre, so 10 kilometre ≈ 10,000 metre.
- 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 Kilometre to Metre converter
Type a number into the Kilometre field and the equivalent in Metre 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 Metre field to convert the other way (metre to kilometre). 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 km = 1,000 m), 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 kilometre-to-metre 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 metre are in 1 kilometre?
- 1 kilometre = 1,000 metre (m). To convert any number of kilometre to metre, multiply by 1,000.
- How do I convert kilometre to metre?
- Multiply the number of kilometre by 1,000. For example, 10 kilometre = 10 × 1,000 = 10,000 metre, and 25 kilometre = 25,000 metre.
- How many kilometre are in 1 metre?
- 1 metre = 0.001 kilometre. So to convert metre back to kilometre, multiply by 0.001.
- What is the formula to convert kilometre to metre?
- metre = kilometre × 1,000. The reverse formula is kilometre = metre × 0.001.
- How much is 100 kilometre in metre?
- 100 kilometre = 100,000 metre. (And 1000 kilometre = 1,000,000 metre.)
- Which is bigger, a kilometre or a metre?
- A kilometre is larger: 1 kilometre = 1,000 metre.
- Is this kilometre to metre converter accurate?
- Yes — every value is computed from the exact 1,000 m per km factor (not rounded look-up tables), and the factors are re-verified automatically on every update.
- Can I convert metre to kilometre too?
- Yes. The converter works both ways — enter a value in either field. 1 metre = 0.001 kilometre.
