Bft = (m/s ÷ 0.836)^(1/1.5)

The Beaufort scale uses a non-linear power relationship with wind speed.

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.

Beaufort Scale

Bft

The Beaufort scale is an empirical wind-force scale from 0 (calm) to 12 (hurricane). Created by Francis Beaufort in 1805, it correlates wind force with observed effects on sea or land. Force 8 (34–40 knots) is a gale; force 12 is above 64 knots.

Real-world: Force 5 (fresh breeze): 17–21 knots, white-caps form. Force 8 (gale): 34–40 knots. Force 12: 64+ knots.

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.

Frequently asked questions

How many Beaufort in a inch per minute?
One inch per minute equals 0.000423 Beaufort.
How do I convert inches per minute to Beaufort?
Multiply the inch per minute value by 0.000423 to get the equivalent in Beaufort.
