Example: 10 in/min × 1.2431e-6 = 1.2431e-5 Ma.

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.

Ma

Mach is the ratio of an object's speed to the local speed of sound. Mach 1 at sea level in standard conditions = 1225 km/h (340.29 m/s). Supersonic starts at Mach 1; hypersonic at Mach 5. The Concorde cruised at Mach 2.04; the X-15 reached Mach 6.7.

Real-world: Concorde: Mach 2.04. F-16 fighter: Mach 2. SR-71 Blackbird: Mach 3.3. Space re-entry: Mach 25+.

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 Mach in a inch per minute?
