aN = MN × 1.000000000e+24

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 Attonewtons

An attonewton (aN) is 10⁻¹⁸ N - the force scale of individual photon recoil and quantum vacuum effects. The thermal noise floor of an AFM cantilever at room temperature is ~1-10 aN/√Hz. A 532 nm photon absorbed by a trapped ion imparts ~0.3 aN of recoil. Casimir forces between conducting surfaces 10-100 nm apart are 1-100 aN. NEMS resonators have demonstrated force sensitivity below 1 aN/√Hz, enabling single-molecule adsorption detection. Optomechanical cavities probe radiation pressure at the attonewton scale to test quantum measurement limits. 1 aN = 10⁻¹⁸ N.
