The three-step method

1. Take your force in newtons. 2. Multiply by 0.2248089431 (the exact reciprocal of 4.4482216153). 3. Round to the precision your application needs — the converter's chips give you 2 to 8 decimal places.

Worked: 365 N × 0.2248089431 = 82.055 lbf. Inverse check: 82.055 × 4.4482216 = 365.0 N ✓.

Avoiding the classic conversion mistakes

Mistake one: multiplying by 4.4482 instead of dividing (result 20× too high — actually 19.8×). Direction check: pounds are bigger than newtons, so the lbs number must be smaller.

Mistake two: converting torque (N·m) with the force factor. If your value has a meter attached, you need 0.7375621 to ft·lb, not 0.2248089 to lbf.
