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.
About Kilowatt-Hours
A kilowatt-hour (kWh) is the energy consumed by 1 kW for one hour - exactly 3,600,000 J = 3.6 MJ. All domestic electricity meters bill in kWh. Appliance benchmarks: fridge 180-250 kWh/year; washing machine 0.5-2.0 kWh/cycle; air conditioner 1-3 kWh/h. EVs consume 13-25 kWh/100 km; the Lucid Air achieves ~15.9 kWh/100 km (WLTP). Producing 1 tonne of primary aluminium requires ~13,000-15,000 kWh. Global electricity generation is ~29,165 TWh ≈ 2.9 × 10¹³ kWh/year. 1 kWh = 3.6 MJ = 3,412.1 BTU = 859.85 kcal.
