Convert Metre to Ken
1 metre = 0.55 ken (ken). For example, 10 metre = 5.5 ken and 100 metre = 55 ken. Type any value below to convert metre to ken both ways — it runs entirely in your browser.
Quick answer: Metre to Ken
1 Metre = 0.55 Ken (m → ken). To convert metre to ken, multiply by 0.55. To convert ken to metre, multiply by 1.818182. 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-ken questions.
How to convert Metre to Ken
To convert metre to ken, multiply the number of metre by the conversion factor 0.55, because 1 m = 0.55 ken. The conversion is linear, so the same factor works for any value — whole numbers, decimals or fractions. For the reverse direction, 1 ken = 1.818182 m, so you divide by 0.55 (or multiply by 1.818182) to turn ken back into metre.
ken = m × 0.55 ·
m = ken × 1.818182
- Write down the value you want to convert, in metre.
- Multiply it by 0.55.
- The result is the same area/length/quantity expressed in ken.

Metre vs Ken: which is bigger?
A ken is the larger unit: one ken equals 1.818182 metres. Put another way, you need 1.818182 metres to make a single ken.
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 Ken? History, origin and usage
The ken is a traditional Japanese unit equal to six shaku (the Japanese 'foot'). The concept came from China, where ken originally meant the space between two pillars; its length varied by era and region until Japan's Weights and Measures Act of 1891 fixed the shaku at 10/33 of a metre, making one ken exactly 60/33 of a metre, about 1.818 m.
The ken remains a familiar term in Japanese architecture, where it governs the spacing of pillars and the sizing of rooms and tatami mats. Rooms are often planned as so many ken by so many ken.
Tatami-mat dimensions and traditional Japanese room sizes are built around the ken, so floor area is still sometimes reckoned in mats. The word originally described the bay between two columns rather than a fixed distance.

Tips for converting Metre to Ken
- To go from metre to ken, multiply by 0.55; to go back, divide by 0.55 (or multiply by 1.818182).
- For a quick mental estimate, remember that 1 metre ≈ 0.55 ken, so 10 metre ≈ 5.5 ken.
- 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 Ken converter
Type a number into the Metre field and the equivalent in Ken 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 Ken field to convert the other way (ken 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 = 0.55 ken), 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-ken conversions because a small rounding error in a published table compounds quickly at larger quantities; computing from the exact factor avoids that.
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.
