The kilogram, symbol kg, is the SI unit of mass. It is defined by taking the fixed numerical value of the Planck constant h to be 6.626 070 15 × 10 −34 when expressed in the unit J⋅s, which is equal to kg⋅m 2 ⋅s −1, where the metre and the second are defined in terms of c and Δν Cs. —
Maintenance can also save fuel: 100 kg (220 lb) more fuel is consumed without an engine wash schedule; 50 kg (110 lb) with a 5 mm (0.20 in) slat rigging gap, 40 kg (88 lb) with a 10 mm (0.39 in) spoiler rigging gap, and 15 kg (33 lb) with a damaged door seal. [37]
TNT equivalent is a convention for expressing energy, typically used to describe the energy released in an explosion.The ton of TNT is a unit of energy defined by convention to be 4.184 gigajoules (1 gigacalorie), [1] which is the approximate energy released in the detonation of a metric ton (1,000 kilograms) of TNT.

When stacked and fully fueled, Starship has a mass of approximately 5,000 t (11,000,000 lb), [c] a diameter of 9 m (30 ft) [12] and a height of 121.3 m (398 ft). [13] The rocket has been designed with the goal of being fully reusable to reduce launch costs; [14] it consists of the Super Heavy booster and the Starship upper stage [15] which are powered by Raptor and Raptor Vacuum engines.

Cooled by the aircraft's slip-stream, the air-cooled 12.7 mm AN/M2 was fitted with a substantially lighter 36-inch (91 cm) length barrel, reducing the weight of the complete unit to 61 pounds (28 kg), [82] [83] which also had the effect of increasing the rate of fire. The full official designation for this weapon was "Browning Machine Gun ...
Kentucky jumped out to a 6–0 lead on a 20-yard touchdown pass from Morgan Newton to Derrick Locke (the conversion failed) but Georgia held a 20–6 lead at halftime. [ 24 ] [ 25 ] In the third quarter, Randall Cobb scored on a 12-yard touchdown run and LaRod King caught a 21-yard touchdown pass from Newton to draw Kentucky to within 27–20.
The iron and steel industry is thus very important economically, and iron is the cheapest metal, with a price of a few dollars per kilogram or pound. Pristine and smooth pure iron surfaces are a mirror-like silvery-gray. Iron reacts readily with oxygen and water to produce brown-to-black hydrated iron oxides, commonly known as rust.
