About Picojoules
A picojoule (pJ) is 10⁻¹² J - the scale of laser pulses in scientific instruments and chip-level capacitor storage. A 1 pF capacitor charged to 1 V stores exactly 0.5 pJ. Laser pulse energies in OCT and ultrafast spectroscopy are typically 1-1,000 pJ. Single-photon SNSPD detector dead-time dissipates 1-100 pJ per event. Phase-change memory cells (PCM, ReRAM) switch at 10-100 pJ per state transition, setting a lower bound on non-volatile memory energy efficiency. 1 pJ = 10⁻¹² J = 6.242 MeV.
About Foot-Pound-Force
A foot-pound-force (ft·lbf) is the work done by one pound-force through one foot - exactly 1.3558179483314004 J. It is the standard torque and energy unit in US engineering. Automotive engine torque: Honda Civic ~125 lb-ft; Ford F-150 EcoBoost ~500 lb-ft. Muzzle energies: .22 LR ~140 ft·lbf; .308 Winchester ~2,600 ft·lbf; .50 BMG ~14,000 ft·lbf. Diesel pile hammers deliver 15,000-600,000 ft·lbf/blow. SAE Grade 8 bolts are specified at 7-950 ft·lbf. 1 ft·lbf = 12 in·lbf = 1.35582 J = 0.32405 cal.
