About Meganewtons

One meganewton (MN) is 10⁶ N ≈ 224,800 lbf - the force scale of rockets, major bridges, and large presses. NASA's SLS Block 1 produces ~35.6 MN combined sea-level thrust. Each suspension cable of the Golden Gate Bridge carries ~350 MN under design load. Aluminium extrusion presses operate at 50-200 MN; the world's largest forging press reaches 750 MN. Offshore jacket platform piles resist wave and mudslide forces in the tens of MN. Seismic base shear on large buildings reaches several MN. Boeing 747 aerodynamic drag at cruise ≈ 0.25 MN. 1 MN = 1,000 kN = 224,809 lbf.

About Poundal

The poundal (pdl) is the force unit of the foot-pound-second absolute system - the force to accelerate 1 pound at 1 ft/s² - approximately 0.1383 N. Introduced in 1877 by Thomson and Tait as the FPS analogue of the CGS dyne (1 dyn = 1 g·cm/s²; 1 pdl = 1 lb·ft/s²). The poundal is distinct from pound-force: since standard gravity = 32.174 ft/s², 1 lbf = 32.174 pdl. It survives in older British engineering texts and early 20th-century thermodynamics literature, but is otherwise obsolete. 1 pdl = 0.138254954376 N = 1/32.174 lbf.
