13,558,180 erg. The foot-pound force (symbol: ft⋅lbf, [1] ft⋅lbf, [2] or ft⋅lb [3]) is a unit of work or energy in the engineering and gravitational systems in United States customary and imperial units of measure. It is the energy transferred upon applying a force of one pound-force (lbf) through a linear displacement of one foot.
Gravitational metric system. ≈ 0.1382550 kgf⋅m. A pound-foot (lb⋅ft), abbreviated from pound-force foot (lbf · ft), is a unit of torque representing one pound of force acting at a perpendicular distance of one foot from a pivot point. [2] Conversely one foot pound-force (ft · lbf) is the moment about an axis that applies one pound-force ...
Square miles should not be confused with miles square, a square region with each side having a length of the value given. For example, a region which is 20 miles square (20 mi × 20 mi) has an area of 400 sq mi; a rectangle of measuring 10 mi × 40 mi also has an area of 400 sq mi, but is not 20 miles square.
It contains past or present structures of any type, at least 300 metres (984 ft) tall, but lower than 400 metres (1,312 ft). Other parts are: List of tallest structures; List of tallest structures – 400 to 500 metres; See the first part for terminology and general introduction. For terminology and notes see the first part of the list.
The centimetre (SI symbol: cm) is a unit of length in the metric system equal to 10−2 metres ( 1 100 m = 0.01 m). To help compare different orders of magnitude, this section lists lengths between 10 −2 m and 10 −1 m (1 cm and 1 dm). 1 cm – 10 millimetres. 1 cm – 0.39 inches. 1 cm – edge of a square of area 1 cm 2.
Buildings and structures in seven cities are included in this list; Los Angeles, San Francisco, San Diego, Long Beach, Sacramento, Burbank and Oakland each have buildings taller than 400 feet (120 m). The tallest building is the Wilshire Grand Center at 1,100 feet (340 m). All of the buildings and structures taller than 500 feet (150 m) are in ...
The pound per square inch (abbreviation: psi) or, more accurately, pound-force per square inch (symbol: lbf/in2), [1] is a unit of measurement of pressure or of stress based on avoirdupois units. It is the pressure resulting from a force with magnitude of one pound-force applied to an area of one square inch. In SI units, 1 psi is approximately ...
The yield of a Tomahawk cruise missile is equivalent to 500 kg of TNT. [21] 4.54 × 10 −4: 581 MWh A real 0.454-kiloton-of-TNT (1.90 TJ) charge at Operation Sailor Hat. If the charge were a full sphere, it would be 1 kiloton of TNT (4.2 TJ). 454 tons of TNT (5 by 10 m (17 by 34 ft)) awaiting detonation at Operation Sailor Hat. 1.8 × 10 −3: ...
