Length converter
Converting feet to kilometers is a small, specific task, but getting it wrong by even a rounding error can throw off a recipe, a shipping quote, a construction cut list, or a homework answer. This page runs a live Feet to Kilometers converter — type a number in ft and get the exact km equivalent instantly, calculated with the standard conversion factor rather than an approximation. One ft equals 0.0003048 km, and the calculator below scales that ratio to any amount you enter.
To convert a value from feet to kilometers, multiply the number of ft by 0.0003048. That figure comes from expressing both units against the same reference — in this case, length are compared through a common length base unit — so the ratio holds no matter how large or small the input is.
Common ft amounts and their km equivalents, rounded to six decimal places for accuracy:
Length conversions come up constantly outside of a classroom. Recipes written for a US audience use units while international ones use metric measurements; travel and navigation mix miles, kilometers, and nautical units depending on the country and mode of transport; and technical fields like engineering, medicine, and manufacturing often require converting between systems to match a spec sheet, a prescription, or a purchase order.
Manual conversion is where mistakes creep in — misplacing a decimal, using an outdated or rounded factor, or mixing up which unit is larger. Because this converter applies the exact multiplier every time, the result for feet to kilometers is consistent whether you're converting a single small number or a large batch of values one at a time.
1 ft equals 0.0003048 km. Multiply any ft value by this factor to get km.
It uses the standard defined conversion factor for feet and kilometers, so results are precise to the rounding shown, not a rough estimate.
Yes — use the swap control in the calculator to reverse the direction and convert kilometers into feet instead.
