Convert kilometres to feet

One kilometre is 3280.8399 feet. To convert any amount, multiply by 3280.8399. Going the other way, one foot is 0.0003048 kilometres.

Multiply the kilometre figure by 3280.8399. So ft = km × 3280.8399. For a quick mental estimate, multiplying by about 3281 gets you within a percent or so, which is close enough for most everyday purposes.

One kilometre is about a 12-minute walk. The kilometre is the standard road-distance unit everywhere except the United States, the United Kingdom and a handful of small territories.

One foot is about the length of a standard ruler. The foot is exactly 0.3048 metres. It survives in aviation worldwide — altitudes are given in feet almost everywhere, including in fully metric countries.

Yes. Since the 1959 international yard and pound agreement, the imperial and metric systems are related by exact definitions rather than measurements — the inch is exactly 25.4 mm and the pound exactly 0.45359237 kg. Everything derived from those, including this conversion, is therefore exact. Round at the end rather than partway through, since rounding km before converting introduces an error the conversion then multiplies.
