About Tons of TNT

A ton of TNT is an energy unit defined as exactly 10⁹ thermochemical calories = 4.184 GJ. The Trinity test (first nuclear weapon, 1945) yielded ~21 kilotons TNT = 87.9 TJ. The Tsar Bomba yielded ~50 megatons TNT = 209 PJ - the largest human-made explosion in history. Hiroshima's Little Boy yielded ~15 kilotons = 62.8 TJ. The Tunguska 1908 airburst released ~10-15 megatons TNT. Earthquake magnitude 6.0 releases ~63 kilotons TNT equivalent in seismic energy. 1 t(TNT) = 4.184 GJ = 4,184 MJ = 1,162.8 kWh.

About Watt-Hours

A watt-hour (Wh) is the energy delivered by 1 watt for one hour - exactly 3,600 J. It is the practical unit for small-scale electrical energy: a 10,000 mAh 5 V power bank stores 50 Wh; a laptop battery holds 50-90 Wh; a smartphone battery holds 10-15 Wh; an AA alkaline cell stores ~3 Wh. LED lamps labelled 9 W save 51 Wh/h over a 60 W incandescent. IATA dangerous-goods rules use Wh as the threshold for lithium batteries in aircraft: cells >20 Wh and batteries >100 Wh need special approval. 1 Wh = 3,600 J = 3.412 BTU.
