Feet to Cm Converter

Need to convert feet to cm? This free online feet to cm converter does it in your browser: type a value in ft and the cm answer appears as you type, alongside the same figure in every other length & distance unit. Foot and Centimetre describe the same quantity on two different scales, so the feet to cm conversion is a single arithmetic step once you know the exact factor. Nothing is uploaded and there is no sign-up — the answer is computed on your device as fast as you can type.

The feet to cm formula

One ft is 30.48 cm:

cm = ft × 30.48
ft = cm × 0.032808

That is the whole feet to cm formula: multiply to go one way, divide — or multiply by the inverse — to come back. The factor is a defined constant rather than a measurement, so a feet to cm conversion done this way carries no uncertainty of its own; the only open question is how many decimal places to display, which is covered further down.

Worked example

10 ft = 304.8 cm. Enter 10 in the box above and you will see exactly that, plus the value carried across the rest of the length scale so you can sanity-check it against a unit you already recognise. It is the quickest way to convert feet to cm when the answer has to be exact rather than estimated.

How to convert feet to cm by hand

1. Write the value down in ft — 25 ft is used here.
2. Multiply it by 30.48, because 1 ft = 30.48 cm.
3. Read the answer: 25 ft = 762 cm.
4. To come back, divide by 30.48, or multiply by 0.032808 instead — 1 cm = 0.032808 ft.

Feet to Cm conversion table

Every figure below comes from the same engine as the box at the top of this page, shown at its Automatic precision, so each row is exactly what you would see after typing that value in. Treat it as a ready-made feet to cm chart for the values people reach for most.

Why convert feet to cm?

feet to cm questions rarely arrive alone: they show up when metric drawings meet imperial hardware — screen sizes, sewing patterns, furniture dimensions and tool settings. In each case a ft reading has to become cm — or be checked against one — before it can be used, and a guessed conversion is how the wrong size gets ordered, the wrong setting gets dialled in or the wrong amount gets poured. This free length converter exists for that moment: the feet to cm answer is exact, the full length table sits one glance away, and everything runs locally in the browser — no sign-up, and none of the values you type are uploaded anywhere.

One ft in every length unit

The 30.48 cm figure the converter shows for 1 ft is one row of this table — the row it defaults to. The others are here so a single reading can be checked against any further length & distance unit without running the conversion twice.

Estimating feet to cm without a calculator

One habit worth keeping is to memorise two anchor points on the feet-to-cm line: 10 ft is 304.8 cm, and 100 ft is 3,048 cm — both computed by the same engine as the converter above, not rounded by hand. With those anchors in mind, a mental feet to cm estimate becomes a matter of proportion: a value between the anchors has an answer between them too, and a mental conversion that lands far outside them is a sign that the factor has almost certainly been inverted. The converter above is there for every time an estimate is not good enough.

Which direction the numbers move

Because 1 ft = 30.48 cm, converting feet to cm increases the size of the number: 100 ft becomes 3,048 cm, while 100 cm becomes 3.2808 ft. If a result moves the other way, the factor has been inverted — the two directions are reciprocals and never the same number.

How many decimals to keep

One ft comes out at 30.48 cm — a figure that ends after 2 decimal places — so Automatic already shows all of it as 30.48, with no digit held back. The menu (Automatic, whole numbers, or 2, 4, 6 and 8 decimal places) is there for when a drawing, a recipe or a specification wants the figure padded to a fixed number of places anyway.

About these units

Length conversions are fixed by international agreement: the inch has been exactly 2.54 centimetres since 1959, which makes every imperial-to-metric distance conversion an exact arithmetic step rather than a measurement.

Converting the other way

Press Swap to turn this into a cm-to-ft converter in place. The inverse factor, 1 cm = 0.032808 ft, is shown in the arithmetic panel so you can check the reverse calculation independently.

More length & distance converters

The same engine also powers Nautical Miles to Km (1 nmi = 1.852 km), Cm to Inches (1 cm = 0.393701 in), Inches to Cm (1 in = 2.54 cm) and every other length pair on this site, so the arithmetic is identical whichever two units you end up needing.
