📐 How Pound-force (lbf) and Newton (N) Relate
In metrology, force quantifies rate of change of momentum according to Newton's second law ($M \cdot L / T^2$). Within this domain, Pound-force (lbf) and Newton (N) originate from SI newtons and gravitational pound-force (lbf). Pound-force relies on standard Earth gravitational acceleration $g_0 = 9.80665\text{ m/s}^2$ ($1\text{ lbf} \approx 4.448222\text{ N}$).
Because both Pound-force and Newton belong to the linear force domain, conversion between them is strictly proportional. The exact conversion factor (4.44822162) guarantees zero precision drift across mathematical calculations.
