Convert Megatons of TNT to Watt-Hours
Convert Megatons of TNT (Mt(TNT)) to Watt-Hours (Wh) instantly and accurately.
Conversion Formula
Wh = Mt(TNT) × 1162222222000
About Megatons of TNT
A megaton of TNT (Mt(TNT)) = 10⁶ tons of TNT = exactly 4.184 PJ. The Soviet Tsar Bomba (1961) yielded ~50 Mt - the largest human-made explosion ever, with a fireball 8 km in diameter. Castle Bravo (1954) yielded ~15 Mt, 2.5× its 6 Mt design yield. Modern thermonuclear warheads typically range from 0.1-1.2 Mt. The 2011 Tōhoku earthquake released ~500 Mt in seismic energy. The Krakatoa 1883 eruption released ~200 Mt; Tambora 1815 ~33,000 Mt. 1 Mt(TNT) = 4.184 PJ = 1,162,800 MWh.
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.
