Convert Feet to Decimetres
1 foot is 3.05 dm. One foot is exactly 3.048 decimetres.
One foot is 3.048 decimetres. To convert feet to decimetres, multiply by 3.048; to go the other way, divide by 3.048 or multiply by 0.32808399. The factor is exact rather than rounded: it follows from NIST. Twelve inches, or exactly 0.3048 meters.

How do you convert feet to decimetres? The converter and the working
- 1.Take the measurement in feet.
- 2.Multiply by 3.048 — that is how many decimetres fit in one foot.
- 3.To go back the other way, divide by 3.048, or multiply by 0.32808399.
Worked example: 25 feet to decimetres
- Formula
- ft × 3.048 = dm
- Arithmetic
- 25 × 3.048 = 76.2 dm
- Answer
- 25 ft = 76.2 dm
The factor is exact, so this figure is exact too — only the display is rounded.

What is a foot?
Twelve inches, or exactly 0.3048 meters. Still the working unit of US construction.
What is a decimetre?
A tenth of a metre. Rare in speech and unavoidable in definitions: the litre is a cubic decimetre, which is where the millilitre and the cubic centimetre meet.
How many decimetres are in a foot?
One foot is 3.048 decimetres, exactly. Going the other way, one decimetre is 0.32808399 feet. Both figures come from the same defined relation rather than from a measurement, which is why they are the same today as they were in 1959.

The whole group — 13 units with their symbols and the size of each one in meters — is on the conversion index, along with every pair it makes. The table above already gives each of them relative to a foot.
