Kilometre and Foot

Kilometres are the road distance nearly everywhere outside the United States and the United Kingdom, which is why converting them is usually about reading a map or a race entry.

A foot is twelve inches, and it is the unit heights and room sizes are quoted in across the United States. Aviation uses it worldwide for altitude, including in countries that use metres for everything else.

Convert km to ft: common questions

How many feet are in a kilometre?

Exactly 3280.83989501. One kilometre is 3280.83989501 feet, and the box above will do it for any figure you type.

Is this conversion exact, or rounded?

The ratio is exact. It is not a rounded constant typed into a table: it is derived from the definitions of the two units, so it agrees with any other correct converter to as many digits as you care to compare.

Why does another converter show a slightly different number?

Almost always rounding rather than disagreement. Many converters cut the answer to two or four decimals, and some carry a factor that was rounded before the multiplication rather than after. The figures here are computed from the exact definitions and only rounded on the way to the screen.
