v gu is the velocity of the small arm expressed in meters per second (m/s). v p is the velocity of the projectile expressed in meters per second (m/s). v c is the velocity of the powder charge expressed in meters per second (m/s). 1000 is the conversion factor to set the equation equal to kilograms.
In engineering and physics, g c is a unit conversion factor used to convert mass to force or vice versa. [1] It is defined as = In unit systems where force is a derived unit, like in SI units, g c is equal to 1.
kilogram per cubic metre (SI unit) kg/m 3: ≡ kg/m 3 = 1 kg/m 3: kilogram per litre kg/L ≡ kg/L = 1000 kg/m 3: ounce (avoirdupois) per cubic foot oz/ft 3: ≡ oz/ft 3: ≈ 1.001 153 961 kg/m 3: ounce (avoirdupois) per cubic inch oz/in 3: ≡ oz/in 3: ≈ 1.729 994 044 × 10 3 kg/m 3: ounce (avoirdupois) per gallon (imperial) oz/gal ≡ oz ...
The SI-unit newton-second (kg⋅m/s, or simply N⋅s), by measuring the mass in kilograms (kg) and velocity in meters per second (m/s). Identically, by multiplying by a factor of 1 ⁄ 1000 the unit gram can be used as input to the formula instead of kilogram, which is useful, since bullet weights often are stated in grams by international ...
(Values in bold face are exact.) 1 g/mm 2 equals exactly 1000 kg/m 2.; 1 kg/cm 2 equals exactly 10 000 kg/m 2.; With the pound and inch legally defined as 0.453 592 37 kg and 0.0254 m respectively, it follows that the (mass) pounds per square inch is approximately:
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.
For example, 10 miles per hour can be converted to metres per second by using a sequence of conversion factors as shown below: = . Each conversion factor is chosen based on the relationship between one of the original units and one of the desired units (or some intermediary unit), before being rearranged to create a factor that cancels out the ...
The fuel consumption is an equivalent measure for cars sold outside the United States, typically measured in litres per 100 km traveled; in general, the fuel consumption and miles per gallon would be reciprocals with appropriate conversion factors, but because different countries use different driving cycles to measure fuel consumption, fuel ...
