Convert Ounce-inches to Dyne-centimeters

Formula

dyn·cm = ozf·in × 70615.51814226

Derivation from SI units:

• 1 ozf·in = 1/16 lbf·in = 0.00706155181 N·m
• 1 dyn·cm = 10⁻⁵ N × 0.01 m = 10⁻⁷ N·m
• 1 ozf·in = 0.007061551814226 N·m ÷ 1 × 10⁻⁷ N·m per dyn·cm = 70615.51814226 dyn·cm

Both units are defined exactly, so the factor is exact. Ounce-inch definition: ounce-inch; Dyne-centimeter definition: dyne-centimeter.

Worked examples

1. A reading of 10 ozf·in converts to 706155.1814 dyn·cm.
   10 ozf·in × 70615.51814 = 706155.1814 dyn·cm
2. A value of 100 ozf·in is 7061551.814 dyn·cm.
   100 ozf·in × 70615.51814 = 7061551.814 dyn·cm

Where it's used

Ounce-inches are used for stepper and servo motor holding torque, while dyne-centimeters appear in rheometers and viscometers (torque readings). Both measure torque (moment of force), so the conversion is a fixed factor.
