About Kilogram-Force
The kilogram-force (kgf), also called the kilopond (kp), is the gravitational force on 1 kg under standard gravity - exactly 9.80665 N. It was the primary force unit in continental European engineering before SI. ISO 1000 (1973) and EU Directive 80/181/EEC deprecated it in favour of the newton. Spring and bathroom scales reading in 'kg' technically measure kgf. Older DIN and JIS materials standards give tensile strength in kgf/mm² (× 9.80665 = MPa). Hydraulic cylinder ratings in legacy European machinery use kgf or tonne-force. 1 kgf = 9.80665 N = 2.20462 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.
