About Microjoules
A microjoule (µJ) is 10⁻⁶ J - the scale of precision laser ablation, ESD damage events, and individual LIDAR pulses. LASIK eye surgery delivers 0.5-2 µJ per pulse at 193 nm, ablating ~0.25 µm of corneal tissue per pulse. ESD events that destroy IC gates correspond to 1-1,000 µJ; the Human Body Model test discharges ~500 µJ at 2 kV. Q-switched microchip laser pulses for rangefinding are 1-100 µJ. The kinetic energy of a 1 mg grain of sand falling 10 cm is mgh ≈ 0.98 µJ. 1 µJ = 10⁻⁶ J.
About Inch-Pound-Force
An inch-pound-force (in·lbf) is the work done by one pound-force through one inch - exactly 0.11298482902761670 J (= 1/12 ft·lbf). It is the dominant torque unit for small fasteners and precision instruments in the US: a #6-32 screw in aluminium is torqued to 4-6 in·lbf; a dental implant abutment screw to ~25-30 Ncm (2.2-2.7 in·lbf). Hobby servo motor torque is quoted in oz·in (1 in·lbf = 16 oz·in). Bicycle stem bolts are typically 4-6 Nm (35-53 in·lbf). 1 in·lbf = 0.11298 J = 1/12 ft·lbf = 11.298 Ncm.
