Feet per second to Knots Converter

Speed conversion · Updated 2026-10-04

Converting feet per second to knots is a multiplication by a fixed factor: 1 ft/s = 0.5924838 kn. 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 per second works out to 0.5924838 kn, the knot is the smaller unit of the two: a figure given in knot always carries a smaller number than the same measurement in foot per second. A chart drawn in ft/s can hide that, so check which label the axis uses before you compare two readings.

Driving and sport are the everyday sources of this pair: a dashboard reading in feet per second against a speed limit posted in knots, or a training plan written in one while a device reports the other.

The conversion factor used here is 0.5924838 kn per foot per second (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/s a factor rounded to three decimals can be off by a measurable amount. The reverse direction uses 1.68781 ft/s per kn, the exact reciprocal, so a round trip through both pages returns your original number.
