About Newtons
The newton (N) is the SI unit of force - the force to accelerate 1 kg at 1 m/s², defined as 1 N = 1 kg·m/s². Named after Sir Isaac Newton and adopted in 1960. One newton is the weight of a ~102 g apple. Everyday forces: gentle finger press ~1 N; handshake 150-200 N; human bite 500-700 N; car emergency braking 5,000-15,000 N; turbofan engine thrust ~300 kN; Boeing 747 lift at cruise ~2,800 kN. The newton is universally used in science and engineering worldwide. 1 N = 1 kg·m/s² = 0.22481 lbf.
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.
