About Metric Ton-Force
One metric tonne-force (tf) is the gravitational force on 1,000 kg under standard gravity - exactly 9,806.65 N = 9.80665 kN. It dominates international heavy engineering: crane hook capacities are rated in tf (a '50-tonne crane' lifts 50 tf = 490.3 kN); ship mooring lines, anchor holding power, and cargo lashing per IMO standards are in tf; hydraulic presses for metal extrusion and stamping in Europe and Asia are rated in tf. ISO 7531 lifting-gear working load limits (WLL) use tf. 1 tf = 1,000 kgf = 9,806.65 N = 2,204.6 lbf.
About Micronewtons
A micronewton (µN) is 10⁻⁶ N - the force scale of satellite microthrusters and MEMS actuators. Ion FEEP microthrusters on CubeSats produce 1-1,000 µN to compensate atmospheric drag at sub-500 km altitudes. Newton's law gives F = Gm₁m₂/r² ≈ 6.674 µN between two 1 kg masses 10 cm apart. Comb-drive electrostatic actuators in lab-on-a-chip devices operate at micronewton forces for cell sorting. AFM cantilevers mapping cell stiffness apply 10-100 µN. Red blood cells deform measurably at ~10-20 µN - an optical tweezers assay used to detect malaria. 1 µN = 10⁻⁶ N.
