The poundal conversion selector on this page selects the force measurement unit to convert to starting from poundals (pdl). To make a conversion starting from a unit of force other than poundal, simply click on the "Reset" button.
The poundal is a unit of force in the foot-pound-second system of units equal to 0.138254954 newtons (1 pdl = 0.138254954 N), the SI derived unit of force.
The poundal (pdl) is also equal to 138,254.954 micronewtons (μN), or 138.254954 millinewtons (mN), 13.8254954 centinewtons (cN), or 0.0138254954 decanewtons (daN) or 1.38254954 × 10-4 kilonewtons (kN), which are units of force in the SI.
The poundal represents the amount of force needed to accelerate a mass of one pound to one foot per second squared:
1 pdl = 1 lb × ft/s2
