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 Δ ν Cs .
Central banks typically hold the standard 400-troy-ounce (438.9-ounce; 27.4-pound; 12.4-kilogram) Good Delivery gold bar in their gold reserves and it is widely traded among bullion dealers. Additionally, the kilobar, weighing 1,000 grams (32.15 troy ounces), and the 100-troy-ounce (109.7-ounce; 6.9-pound; 3.1-kilogram) gold bar are popular for ...
The gram (originally gramme; [1] SI unit symbol g) is a unit of mass in the International System of Units (SI) equal to one thousandth of a kilogram.. Originally defined in 1795 as "the absolute weight of a volume of pure water equal to the cube of the hundredth part of a metre [1 cm 3], and at the temperature of melting ice", [2] the defining temperature (≈0 °C) was later changed to 4 °C ...
There are gram calories and kilogram calories. One kilogram calorie, which equals one thousand gram calories, often appears capitalised and without a prefix (i.e. Cal) when referring to "dietary calories" in food. [17] It is common to apply metric prefixes to the gram calorie, but not to the kilogram calorie: thus, 1 kcal = 1000 cal = 1 Cal.
The 76–79 in (190–200 cm) fan had 20 titanium blades, and moved 1,369 lb (621 kg) of air per second in climb. The conventional 3-stage LP compressor was followed by a 5-stage, 12:1 HP compressor fitted with 700 blades inspired by the military ATEGG program's low aspect-ratio airfoils.
one kilogram (kg) is 1000 grams; one kilometre (km) is 1000 metres; one kilojoule (kJ) is 1000 joules; one kilolitre (kL) is 1000 litres; one kilobaud (kBd) is 1000 bauds; one kilohertz (kHz) is 1000 hertz; one kilodalton (kDa) is 1000 daltons; one kilobit (kb) is 1000 bits; one kilobyte (kB) is 1000 bytes; one kiloohm is (kΩ) is 1000 ohms
The SI prefix for a thousand units is "kilo-", abbreviated to "k"—for instance, a kilogram or "kg" is a thousand grams. This is sometimes extended to non-SI contexts, such as "ka" being used as a shorthand for periods of 1000 years. In computer science, however, "kilo-" is used more loosely to mean 2 to the 10th power (1024).
The kilogram is the only standard unit to include an SI prefix (kilo-) as part of its name. The gram (10 −3 kg) is an SI derived unit of mass. However, the names of all SI mass units are based on gram , rather than on kilogram ; thus 10 3 kg is a megagram (10 6 g), not a * kilokilogram .
