Notes:

 

(1) The international system of units, Système International d'Unités, SI, was established by the eleventh General Conference on Weights and Measures in 1960, and extended at the 1980 conference.

      There are seven base units, two dimensionless supplementary units and a set of prefixes for decimal scaling.  These may be combined to give compound units. Some compound units have

      special names, and are called derived Units.

 

(2) When documenting compound SI units, each symbol for each base unit has been separated from the others by a space.  There is no space between the unit and any prefix or exponent.

      Any prefix establishes a new unit to which any exponent applies (e.g. km2 = (km)2 = m6 not k(m2) = m5). Prefixes must be in the case specified.  The full name of the unit must not start

      with an upper case letter. If the solidus (/) is used, there must be only one.  There is no space before or after it.

 

(3) Prefixes beyond exa and atto have been proposed but not yet adopted.  Use of the prefixes hecto, deka, deci and centi is discouraged.

 

(4) Prefixes generally should not be used with units having non-decimal multiples and sub-multiples, such as units of time and angle, or with knots and nautical miles.

 

(5) Non-WMO abbreviations with limited character sets taken from ISO 2955-1983.  Other abbreviations try to be consistent with this.

 

(6) The decibel is one tenth of a bel, which is the decimal logarithm of a ratio of two powers.  Frequently, suffixes are supplied to indicate information about one of the

      quantities in the ratio, such as dB(mW), dBm, dBW, dBmW, dB(μV/m).  It is recommended that only dB is used, with the full meaning of the ratio explained, including

      reference levels.

 

(7) This list consists of the units not mentioned previously that occur in existing WMO Manuals.

 

(8) The abbreviation for degrees Celsius proposed for WMO use, C, could be confused with Coulombs.  In this case, Amperes second should be used instead.

 

(9) Dobson Unit = DU.   One Dobson Unit corresponds to a layer of 0.01 mm of pure ozone, if the whole column of atmosphere were compressed at P=1013 hPa and T = 0°C.
