1. Kiloton (TNT equivalent)
Units & Measurements · Metric and SI Unit Abbreviations
Explosive energy equal to one thousand tons of TNT, about 4.184 terajoules, the standard measure of nuclear weapon yields below the megaton range. The Hiroshima bomb released about 15 kt and the Nagasaki bomb about 21 kt.
Example: Seismologists estimated the underground test at roughly 10 kt.
The scale measures energy, not mass: no TNT is involved, and one ton of TNT is defined as exactly 10^9 calories. Large accidental blasts are compared the same way; the 2020 Beirut port explosion was estimated at somewhere around 0.5 to 1 kt. Elsewhere kt can mean knot in aviation or karat for gold, so context decides.
2. Knot (aviation)
Units & Measurements · Engineering Unit Abbreviations
The form of knot used in aviation, US weather products and many marine forecasts, often pluralized as kts. Airspeeds, wind reports and air traffic control instructions worldwide are given in knots.
Example: Wind 240 at 18 kt gusting 30; expect a crosswind on runway 31.
Aircraft manuals distinguish KIAS (knots indicated airspeed) from KTAS (knots true airspeed). Airliners typically approach to land at about 130 to 150 kt. In METAR weather codes the unit follows the digits, as in 24018G30KT. Kt can also mean kiloton or karat, so context decides.
3. Knowledge transfer (KT)
Business & Finance · Management & Strategy Abbreviations
Structured handover of skills, information and documentation from one person or team to another, for example when an employee leaves, a project moves into operations or work is outsourced. KT sessions often include walkthroughs, shadowing and written runbooks.
Example: Two weeks of KT with the outgoing vendor are scheduled before our team takes over support.
"KT sessions" and "KT plan" are especially common in Indian IT services and outsourcing contracts. In academia, knowledge transfer also means moving research into commercial use, often through licensing or spin-out companies.
4. Knight (Kt.)
Writing & Everyday · Title and Honorific Abbreviations
Shows that a man holds a knighthood, added after the name in some reference works, particularly for knights bachelor, who belong to no order of chivalry. Knights are addressed as "Sir."
Example: Biographical directories may style a knight bachelor as Sir Thomas Reid, Kt., to show he holds no order.
Knights Bachelor are the oldest form of British knighthood, and since they carry no order's post-nominal letters, Kt. is sometimes added, though it is not officially required. Knights of an order use its letters instead, such as KBE. Women receive damehoods, and honorary knighthoods given to foreign citizens do not confer the title "Sir."
