About These Units

Poundal (pdl)

A poundal (pdl) is the FPS unit of force equal to 0.138 newtons—the force needed to accelerate 1 pound by 1 ft/s². Poundals avoid confusion between pound-mass and pound-force. Rarely used today; appears in older physics textbooks.

Millinewton (mN)

A millinewton (mN) equals 0.001 newtons or approximately 0.1 gram-force. Millinewtons measure small forces in precision instruments, insect wing forces, and microelectromechanical systems (MEMS). Ion thrusters produce forces in the millinewton range.
