About Converting Foot per Minutes to Knots
Foot per Minutes and Knots both describe speed, and the conversion matters whenever a maritime or aviation speed (knots) needs to be compared against a road speed (mph). Specifically: Distance divided by time, and a knot is one nautical mile per hour.
Formula
knots = foot per minutes × 0.0098747300216
This factor comes from each unit's defined relationship to the category's base unit: 1 foot per minutes equals 0.00508 base units, and 1 knots equals 0.514444444444 base units, so dividing one by the other gives the direct foot per minutes-to-knots factor of 0.0098747300216.
Simple example
1 ft/min × 0.009874730022 = 0.00987473 kn
1 foot per minutes = 0.00987473 knots.
Real-world example
10 ft/min × 0.009874730022 = 0.0987473002 kn
10 foot per minutes = 0.0987473002 knots.

Understanding the Foot per Minutes (ft/min)
Distance divided by time.
Understanding the Knots
Knots (kn) measures speed. A knot is one nautical mile per hour; since the nautical mile is exactly 1,852 meters, a knot is exactly 1,852/3,600 m/s. It is classified as a Non-SI unit accepted for use with SI (maritime/aviation).
Where it's used: Used internationally in maritime navigation and aviation
Uses of the Knots today
- Ship and boat speed in marine navigation
- Aircraft airspeed and wind speed reporting in aviation
- Marine weather forecasts (wind speed)
History of the Knots
The knot gets its name from an old nautical method of measuring speed: sailors trailed a 'log line' with evenly spaced knots behind a ship and counted how many knots paid out over a fixed time, giving a direct speed reading in 'knots.'
The nautical mile it's based on was itself standardized internationally in 1929 (the International Nautical Mile, 1,852 m exactly), tying the knot to a precise value still used in shipping and aviation today.
Historical origin. Knots was not the invention of a single named person; it developed through the process described above.

Frequently asked questions
How many knots are in 1 foot per minutes?
1 foot per minutes equals 0.00987473 knots, using the exact defined conversion factor rather than an estimate.
How do I convert foot per minutes to knots?
Multiply the foot per minutes value by 0.009874730022. The converter above does this instantly to whatever precision you set.
How do I convert knots back to foot per minutes?
Use the reverse factor: 1 knots equals 101.2685914 foot per minutes. You can also use the swap control in the converter above to flip the direction instantly.
What is a foot per minutes?
Foot per Minutes (ft/min) is a unit of speed.
What is a knots?
Knots (kn) measures speed. A knot is one nautical mile per hour; since the nautical mile is exactly 1,852 meters, a knot is exactly 1,852/3,600 m/s. It is classified as a Non-SI unit accepted for use with SI (maritime/aviation).
Is the foot per minutes to knots conversion exact?
Yes. A knot is one nautical mile per hour; since the nautical mile is exactly 1,852 meters, a knot is exactly 1,852/3,600 m/s. That fixed definition is what the converter above uses, so any rounding you see is a display choice, not a limitation of the math.
