About Kilotons of TNT
A kiloton of TNT (kt(TNT)) = 10³ tons of TNT = exactly 4.184 TJ. It is the standard unit for sub-megaton nuclear weapon yields. Hiroshima's Little Boy: ~12-18 kt; Nagasaki's Fat Man: ~19-23 kt. The W88 warhead (Trident II) is ~475 kt; the W76 is ~100 kt. The Beirut port explosion (2020): estimated 0.5-1.1 kt. A magnitude 5.0 earthquake releases ~0.5-2 kt of seismic energy. A kiloton blast creates a fireball ~90-100 m radius and a lethal thermal radius of ~1-2 km. 1 kt(TNT) = 4.184 TJ = 1,162.8 MWh.
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.
