Explanation

Formula: Newton-meters = Pound-feet × 1.355818. Why: this is a cross-system torque conversion. The calculator normalizes the value through newton-meters, then applies the exact target-unit constant for consistent mechanical and engineering use.

Pound-feet (lbf·ft): an imperial torque unit common in automotive, machinery, and fastener specifications.

Newton-meters (N·m): the SI derived unit of torque, expressing rotational force as force applied through a lever arm distance.

This route is useful when translating torque values across SI, imperial, and kilogram-force conventions so fastener specs, drivetrain ratings, and mechanical calculations stay comparable.

This conversion is purely multiplicative because both units reduce through newton-meters using fixed torque definitions with no offset.
