The pound or pound-mass is a unit of mass used in both the British imperial and United States customary systems of measurement.Various definitions have been used; the most common today is the international avoirdupois pound, which is legally defined as exactly 0.453 592 37 kilograms, and which is divided into 16 avoirdupois ounces.

Conversions between units in the metric system are defined by their prefixes (for example, 1 kilogram = 1000 grams, 1 milligram = 0.001 grams) and are thus not listed in this article. Exceptions are made if the unit is commonly known by another name (for example, 1 micron = 10 −6 metre).
In France it used to be defined as 100 livres (pounds), about 48.95 kg (108 lb), and has been redefined as 100 kg (mesures usuelles), thus called metric quintal with symbol qq. In Spain , the quintal is still defined as 100 libras , or about 46 kg (101 lb), but the metric quintal is also defined as 100 kg; [ 3 ] In Portugal a quintal is 128 ...
1 kg = (299 792 458) 2 / (6.626 070 15 × 10 −34)(9 192 631 770) h Δν Cs / c 2 . All units in the SI can be expressed in terms of the base units, and the base units serve as a preferred set for expressing or analysing the relationships between units.
Except for the early prefixes of kilo-, hecto-, and deca-, the symbols for the prefixes for multiples are uppercase letters, and those for the prefixes for submultiples are lowercase letters. [ 8 ] All of the metric prefix symbols are made from upper- and lower-case Latin letters except for the symbol for micro , which is uniquely a Greek ...
The conversion in SI units is 1 ksi = 6.895 MPa, or 1 MPa = 0.145 ksi. The megapound per square inch (Mpsi) is another multiple equal to a million psi. It is used in mechanics for the elastic modulus of materials, especially for metals. [5] The conversion in SI units is 1 Mpsi = 6.895 GPa, or 1 GPa = 0.145 Mpsi.
Jacksonville's defense is unlikely to get in the way of this surging duo, and Okonkwo offers some goal-line equity, too — remember he had a 2-point conversion catch last week en route to a TE2 ...
The modern metric arroba used in these countries in everyday life is defined as 15 kilograms (33 lb). In Colombia, Ecuador, and Peru the arroba is equivalent to 12.5 kilograms (28 lb). [2] In Bolivia nationally it is equivalent to 30.46 litres (6.70 imp gal; 8.05 US gal).
