•  Torr

  The torr is a non-SI unit of pressure defined as ⁄760 of a standard atmosphere, chosen to be roughly equal to the fluid pressure exerted by a millimeter of mercury, i.e. a pressure of 1 Torr is approximately equal to 1 mmHg. Note that the symbol is spelled exactly the same as the unit, but the symbol is capitalized, as is customary in metric units derived from names.

•  Tonne

  The tonne (unit symbol t) or metric ton, also referred to as a metric tonne, is a unit of mass equal to 1,000 kg or approximately the mass of one cubic metre of water at four degrees Celsius. It is sometimes abbreviated as mt in the United States, but this conflicts with other SI symbols. The tonne is not a unit in the International System of Units (SI), but is accepted for use with the SI. In SI units and prefixes, the tonne is a megagram (Mg).

•  Hectare

  A hectare is a unit of area equal to 10,000 square metres (107,639 sq ft), or one square hectometre (100 metres, squared), and is commonly used for measuring land area. Its base unit, the are, was defined by older forms of the metric system, but is no longer part of the modern metric system known as the International System of Units (SI). The International Committee for Weights and Measures (CIPM) classifies the hectare as a unit that is accepted for use with SI.

•  Barn (unit)

  A barn (symbol b) is a unit of area. Originally used in nuclear physics for expressing the cross sectional area of nuclei and nuclear reactions, today it is used in all fields of high energy physics to express the cross sections of any scattering process. A barn is defined as 10 m or 100 square femtometers (fm) and is approximately the cross sectional area of a uranium nucleus.

•  Sverdrup

  The sverdrup, named in honour of the pioneering oceanographer Harald Sverdrup, is a unit of measure of volume transport. It is used almost exclusively in oceanography, to measure the transport of ocean currents. Its symbol is Sv. Note that the sverdrup is not an SI unit, and that its symbol conflicts with the sievert's. It is equivalent to 10 cubic metres per second (0.001 km/s, or about 264 million U.S. gallons per second).

•  Dioptre

  A dioptre, or diopter, is a unit of measurement of the optical power of a lens or curved mirror, which is equal to the reciprocal of the focal length measured in metres (that is, 1/metres). For example, a 3-dioptre lens brings parallel rays of light to focus at ⁄3 metre. The same unit is also sometimes used for other reciprocals of distance, particularly radii of curvature and the vergence of optical beams. The term was proposed by French ophthalmologist Felix Monoyer in 1872.

•  Ångström

  The ångström or angstrom is an internationally recognized unit of length equal to 0.1 nanometre or 1 × 10 metres. It is named after Anders Jonas Ångström. Although accepted for use, it is not formally defined within the International System of Units (SI). The ångström is often used in the natural sciences for expressing the sizes of atoms, lengths of chemical bonds and the wavelengths of electromagnetic radiation, and in technology for the dimensions of parts of integrated circuits.

•  Curie

  The curie (symbol Ci) is a unit of radioactivity, defined as 1 Ci = 3.7×10 decays per second or becquerels. This is roughly the activity of 1 gram of the radium isotope Ra, a substance studied by the pioneers of radiology, Marie and Pierre Curie. The curie has since been replaced by an SI derived unit, the becquerel (Bq), which equates to one decay per second. Therefore: 1 Ci = 3.7×10 Bq and 1 Bq = 2.70×10 Ci The unit is named after Pierre and Marie Curie.

•  Röntgen

  The röntgen or roentgen (symbol R) is a unit of measurement for ionizing radiation, and is named after the German physicist Wilhelm Röntgen. Adopted in 1928, 1 R is the amount of radiation required to liberate positive and negative charges of one electrostatic unit of charge (esu) in 1 cm³ of dry air at standard temperature and pressure (STP). This corresponds to the generation of approximately 2.08×10 ion pairs.

•  Jansky

  In radio astronomy, the flux unit or jansky (symbol Jy) is a non-SI unit of spectral electromagnetic flux density equivalent to 10 watts per square metre per hertz. The flux density or monochromatic flux,, of a source is the integral of the spectral radiance,, over the source solid angle: The unit is named after pioneering US radio astronomer Karl Guthe Jansky, and is defined as: The flux density in Jy can be converted to a magnitude basis, for suitable assumptions about the spectrum.
