How to Convert Torque Units
Torque is force times lever arm. One pound-foot is 4.4482216 N acting at 0.3048 m, which is about 1.355818 N·m.
N·m = lbf·ft × 1.355818 lbf·in = lbf·ft × 12 N·m = lbf·in × 0.1129848

Tips
Check which unit your torque wrench is set to: 25 ft-lb is 300 in-lb, and mixing them up is a common way to strip threads. See the bolt torque calculator for tightening values.
