Handy Factors For Common Calculations

Calculating Pitch Speed:
RPM X Pitch Inches x .0009469 = MPH Pitch Speed

Convert wing area from square decimeters (dm) to Square Inches and back:
Sq dm x 15.5 = Square Inches
Square Inch x .064516 = Square dm

Servo Torque:
KG CM x 13.887 = Inch Ounces
Inch Ounces x .072 = KG CM

Ounces & Grams:
Grams X .03527 = Ounces
Ounces X 28.3495 = Grams
