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-foot questions.
How to convert Decimetre to Foot
To convert decimetre to foot, multiply the number of decimetre by the conversion factor 0.328084, because 1 dm = 0.328084 ft. The conversion is linear, so the same factor works for any value — whole numbers, decimals or fractions. For the reverse direction, 1 ft = 3.048 dm, so you divide by 0.328084 (or multiply by 3.048) to turn foot back into decimetre.
ft = dm × 0.328084 ·
dm = ft × 3.048
- Write down the value you want to convert, in decimetre.
- Multiply it by 0.328084.
- The result is the same area/length/quantity expressed in foot.

Decimetre vs Foot: which is bigger?
A foot is the larger unit: one foot equals 3.048 decimetres. Put another way, you need 3.048 decimetres to make a single foot.
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 Foot? History, origin and usage
The foot is one of the most ancient units, based on the length of a human foot, and appeared in the Greek, Roman, Chinese and English systems with values ranging from about 250 to 335 mm. The English foot was eventually fixed at 12 inches, and since the 1959 international agreement it equals exactly 0.3048 metres.
The foot is still used in the US and UK for human height, building dimensions and, worldwide, aviation altitudes, since pilots almost everywhere report altitude in feet. It divides into 12 inches, and three feet make a yard.
Aircraft altitudes are measured in feet even in fully metric countries, a legacy of aviation's English-speaking origins. Historically the foot's length differed not only between countries but sometimes between trades within a single city.

Tips for converting Decimetre to Foot
- To go from decimetre to foot, multiply by 0.328084; to go back, divide by 0.328084 (or multiply by 3.048).
- For a quick mental estimate, remember that 1 decimetre ≈ 0.328084 foot, so 10 decimetre ≈ 3.28084 foot.
- 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 Foot converter
Type a number into the Decimetre field and the equivalent in Foot 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 Foot field to convert the other way (foot 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 = 0.328084 ft), 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-foot conversions because a small rounding error in a published table compounds quickly at larger quantities; computing from the exact factor avoids that.
Sources
- NIST Special Publication 811 — Guide for the Use of the SI — publishes the exact metric equivalents of the customary units. The inch, foot, yard and mile are defined exactly in metres by the 1959 international yard-and-pound agreement, so every imperial figure on this page is exact, not rounded.
- 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.
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.
