Quick answer: Decimetre to Chain
1 Decimetre = 0.00497097 Chain (dm → ch). To convert decimetre to chain, multiply by 0.00497097. To convert chain to decimetre, multiply by 201.168. 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 decimetre-to-chain questions.
How to convert Decimetre to Chain
To convert decimetre to chain, multiply the number of decimetre by the conversion factor 0.00497097, because 1 dm = 0.00497097 ch. The conversion is linear, so the same factor works for any value — whole numbers, decimals or fractions. For the reverse direction, 1 ch = 201.168 dm, so you divide by 0.00497097 (or multiply by 201.168) to turn chain back into decimetre.
ch = dm × 0.00497097 ·
dm = ch × 201.168
- Write down the value you want to convert, in decimetre.
- Multiply it by 0.00497097.
- The result is the same area/length/quantity expressed in chain.

Decimetre vs Chain: which is bigger?
A chain is the larger unit: one chain equals 201.168 decimetres. Put another way, you need 201.168 decimetres to make a single chain.
What is a Decimetre? History, origin and usage
The decimetre is the metre divided by ten, using the prefix 'deci-' from the Latin decimus, 'tenth'. It was one of the original submultiple prefixes introduced with the metric system in France in 1795.
The decimetre is rarely used in everyday speech, overshadowed by the centimetre and the metre. It appears mostly in classrooms illustrating decimal place value, though it stays quietly relevant because a cubic decimetre is exactly one litre.
Because a cubic decimetre equals one litre, the decimetre underpins the metric measurement of liquid volume. Its prefix 'deci-' is Latin, unlike the Greek-derived prefixes used for the larger metric steps.
What is a Chain? History, origin and usage
The chain was introduced in 1620 by the English clergyman and mathematician Edmund Gunter, who built a 66-foot iron chain of 100 links to make land surveying accurate and decimal-friendly. It cleverly reconciled the old four-based English units with decimal arithmetic, since ten square chains make exactly one acre.
Gunter's chain became the basis of property surveys across England and the British Empire and shaped the rectangular land grids of the United States and Canada. Though largely obsolete, it still turns up in old deeds and, famously, as the length of a cricket pitch.
A cricket pitch is exactly one chain, or 22 yards, long. Eighty chains make a mile, and because ten square chains equal one acre the design simplified land calculations for centuries.

Tips for converting Decimetre to Chain
- To go from decimetre to chain, multiply by 0.00497097; to go back, divide by 0.00497097 (or multiply by 201.168).
- For a quick mental estimate, remember that 1 decimetre ≈ 0.00497097 chain, so 10 decimetre ≈ 0.0497097 chain.
- 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 Decimetre to Chain converter
Type a number into the Decimetre field and the equivalent in Chain 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 Chain field to convert the other way (chain to decimetre). 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 dm = 0.00497097 ch), 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 decimetre-to-chain 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.
Frequently asked questions
