Surface Speed
SFM = (Pi * Dia * RPM) / 12

Dia = Diameter (inches)
RPM = Revs Per Minute
SFM = Surface Feet Per Minute

Chip Load
CL = IPM / RPM * Teeth

CL = Chip Load (IPR per Tooth)
IPR = Inches Per Rev
IPM = Inches Per Minute
RPM - Revs Per Minute
Teeth = # of teeth per cutter

(Hint: For lathes, Teeth = 1)

Inch / Millimeter
.03936" = 1mm
25.4mm = 1"

Farenheit / Celsius
(°F - 32) * 5/9 = °C
(°C * 9/5) + 32 = °F
