About both units

From

Inch per Minute

in/min

Inches per minute (in/min) is used in CNC machining, 3D printing, some flow-rate specifications and US plant growth studies. CNC cutting feed rates are typically 10–100 in/min.

Real-world: CNC aluminum cut: 20–60 in/min. 3D printer travel: 60–200 in/min. Plant growth: fractions of in/min × time.

Knot

kn

The knot equals one nautical mile per hour — 1.852 km/h. It is the international standard in marine navigation and aviation. Commercial airliners cruise at 450–500 knots. Sailboats in light breeze: 2–6 knots.

Real-world: Airbus A380 cruise: ~490 knots. Cruise ship: 20 knots. Sailing yacht: 6 knots typical.

Tips & common mistakes

Quick tips

  • 1 in/min = 0.000423 m/s = 0.0254 m/min.
  • CNC: lower in/min for harder materials; higher for softer.
  • Always match tool speed and material — too fast breaks bits.

Avoid these

  • Using mm/min and in/min interchangeably in CNC — 25.4× difference.
  • Treating 100 in/min as fast — only moderate in CNC.
  • Confusing feed rate with spindle RPM.
