ConvBolt — Unit ConverterFeet to Kilometers Converter
Converting feet to kilometers is a multiplication by a fixed factor: 1 ft = 0.0003048 km. The table below covers the values people look up most often, and the formula section shows exactly where that factor comes from.
Because one foot works out to 0.0003048 km, the kilometer is the far smaller unit of the two: a figure given in kilometer always carries a smaller number than the same measurement in foot. A chart drawn in ft can hide that, so check which label the axis uses before you compare two readings.
Technical documentation is the other common source — a datasheet drawn up in feet often has to be re-expressed in kilometers for a supplier or a regulator who works in the other system.
The conversion factor used here is 0.0003048 km per foot (7 significant digits as shown). Kept to seven figures it covers professional measurement; if you round it to two or three decimals for a spreadsheet, the error scales with the input — at a value of 1,000 ft a factor rounded to three decimals can be off by a measurable amount. The reverse direction uses 3280.84 ft per km, the exact reciprocal, so a round trip through both pages returns your original number.

How to convert feet to kilometers
Multiply the foot value by 0.0003048 to get the equivalent in kilometers. This single factor works for every value in the table above and for anything else you need — there is no per-value adjustment, which is why a conversion table and a calculator always agree.
If you need the opposite direction, use the Kilometers to Feet converter instead of dividing by hand; both pages use the same source factors. For every other ft conversion in one place, see the ft conversion hub.
