A typical turbocharged V8 diesel engine might have an engine power of 250 kW (340 hp) and a mass of 380 kg (840 lb), [1] giving it a power-to-weight ratio of 0.65 kW/kg (0.40 hp/lb). Examples of high power-to-weight ratios can often be found in turbines. This is because of their ability to operate at very high speeds.
The kilogram is the only base SI unit with an SI prefix (kilo) as part of its name. The word kilogramme or kilogram is derived from the French kilogramme, [15] which itself was a learned coinage, prefixing the Greek stem of χίλιοι khilioi "a thousand" to gramma, a Late Latin term for "a small weight", itself from Greek γράμμα. [16]
Both HE (9.1 kg (20 lb)) and smoke (10.2 kg (22 lb)) ammunition was used. Smoke included WP and Base Ejection, and in World War II other types for practice. Two charges were available. In World War II, both streamlined and cylindrical bombs were available.
For example, Concorde cruised at 1354 mph, or 7.15 million feet per hour, with its engines giving an SFC of 1.195 lb/(lbf·h) (see below); this means the engines transferred 5.98 million foot pounds per pound of fuel (17.9 MJ/kg), equivalent to an SFC of 0.50 lb/(lbf·h) for a subsonic aircraft flying at 570 mph, which would be better than even ...
Acceleration from 0 to 100 km/h (62 mph) takes 3.4 seconds and the top speed is 323 km/h (201 mph). It has the same 7-speed Lamborghini Doppia Frizione (LDF) dual-clutch transmission as that of the coupé. The Spyder has a dry weight of 1,542 kg (3,400 lb) which is 120 kg (265 lb) more than the coupé due to chassis reinforcing components.

The MERU, or Milli Earth Rate Unit, is an angular velocity equal to 1/1000 of Earth's rotation rate. It was introduced by MIT's Instrumentation Laboratories (now Draper Labs) to measure the performance of inertial navigation systems. [82] One MERU = 7.292 115 × 10 ^ −8 radians per second [83] or about 0.2625 milliradians/hour.
The weight has been reduced to 9.27 kg (20.4 lb), 2.23 kg (4.9 lb) lighter than the M/62. Its rate of fire of around 500–650 rounds per minute (RPM) [ 31 ] is significantly less than the Danish M/62's 1,200 RPM, but it allows for better control, greater accuracy, more conservation of ammunition, more versatile firing positions, and less risk ...
