About Milligram-Force
One milligram-force (mgf) is the gravitational force on 1 mg under standard gravity - exactly 9.80665 × 10⁻⁶ N. It is the natural unit for ultra-precise analytical balances: a 0.001 mg readability balance resolves ~9.8 nN = 0.001 mgf. MEMS force sensors in precision weighing cells are specified in mgf. Watchmaking uses mgf gauges to measure hairspring and detent actuation forces. Entomology and microbiology measure insect and microorganism attachment forces in mgf. Aerospace composite strain sensors are calibrated with mgf reference weights. 1 mgf = 9.80665 µN = 0.980665 dyn.
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.
