⚡ Direct Answer: 1 lb·ft to N·m
1 Pound-foot (lb·ft) equals exactly 1.35582 Newton-meter (N·m).
To convert from Pound-foot to Newton-meter, multiply the quantity by 1.35582 (or divide by 0.737561).
📐 How Pound-foot (lb·ft) and Newton-meter (N·m) Relate
In metrology, torque quantifies rotational moment and torsional force ($F \cdot L$). Within this domain, Pound-foot (lb·ft) and Newton-meter (N·m) originate from SI newton-meters and imperial foot-pounds (lbf·ft). Standardized under ISO 80000-4 mechanical engineering metrology ($1\text{ N}\cdot\text{m} \approx 0.737562\text{ lbf}\cdot\text{ft}$).
Because both Pound-foot and Newton-meter belong to the linear torque domain, conversion between them is strictly proportional. The exact conversion factor (1.35582) guarantees zero precision drift across mathematical calculations.
