It is named after the English physicist James Prescott Joule (1818-1889). 2 2 2017-08-10 12:25:40.0 accepted false SDN:P06::JPKG SDN:P06::JPKG 2009-06-11 12:04:27.0 SDN:P06::JPKG Joules per kilogram J/kg Unavailable 1 1 2009-06-11 12:04:27.0 accepted false SDN:P06::JKGK SDN:P06::JKGK 2009-06-11 12:14:23.0 SDN:P06::JKGK Joules per kilogram per Kelvin J/kg/K Unavailable 1 1 2009-06-11 12:14:23.0 accepted false SDN:P06::JCMH SDN:P06::JCMH 2015-01-28 09:30:37.0 SDN:P06::JCMH Joules per square centimetre per day J/cm^2/d Radiant energy per 10^-4 SI unit area over a period of one day. 1 1 2015-01-28 09:30:37.0 accepted false SDN:P06::JMSQ SDN:P06::JMSQ 2009-06-11 12:20:04.0 SDN:P06::JMSQ Joules per square metre J/m^2 Unavailable 1 1 2009-06-11 12:20:04.0 accepted false SDN:P06::KPAS SDN:P06::KPAS 2009-06-11 12:22:08.0 SDN:P06::KPAS Kelvin Pascals per second K.Pa/s Unavailable 1 1 2009-06-11 12:22:08.0 accepted false SDN:P06::KMTX SDN:P06::KMTX 2009-06-11 12:22:54.0 SDN:P06::KMTX Kelvin metres K.m Unavailable 1 1 2009-06-11 12:22:54.0 accepted false SDN:P06::KMTS SDN:P06::KMTS 2009-06-11 12:23:52.0 SDN:P06::KMTS Kelvin metres per second K.m/s Unavailable 1 1 2009-06-11 12:23:52.0 accepted false SDN:P06::KPMT SDN:P06::KPMT 2009-06-11 12:25:09.0 SDN:P06::KPMT Kelvin per metre K/m Unavailable 1 1 2009-06-11 12:25:09.0 accepted false SDN:P06::KPRS SDN:P06::KPRS 2009-06-11 12:31:51.0 SDN:P06::KPRS Kelvin per second K/s Unavailable 1 1 2009-06-11 12:31:51.0 accepted false SDN:P06::KSXX SDN:P06::KSXX 2009-06-11 12:31:02.0 SDN:P06::KSXX Kelvin second K.s Unavailable 1 1 2009-06-11 12:31:02.0 accepted false SDN:P06::KMSS SDN:P06::KMSS 2009-06-11 12:39:22.0 SDN:P06::KMSS Kelvin square metres per kilogram per second K.m^2/kg/s Unavailable 1 1 2009-06-11 12:39:22.0 accepted false SDN:P06::KLSQ SDN:P06::KLSQ 2009-06-11 14:48:06.0 SDN:P06::KLSQ Kelvin squared K^2 Unavailable 1 1 2009-06-11 14:48:06.0 accepted false SDN:P06::KGPS SDN:P06::KGPS 2009-06-11 13:21:36.0 SDN:P06::KGPS Kilogram per second kg/s Unavailable 1 1 2009-06-11 13:21:36.0 accepted false SDN:P06::KGXX SDN:P06::KGXX 2017-07-26 17:31:20.0 SDN:P06::KGXX Kilograms kg The SI standard unit of mass. 2 2 2017-07-26 17:31:20.0 accepted false SDN:P06::UKMC SDN:P06::UKMC 2003-11-05 15:13:12.0 SDN:P06::UKMC Kilograms per cubic metre kg/m^3 Unavailable 1 1 2003-11-05 15:13:12.0 accepted false SDN:P06::KSP3 SDN:P06::KSP3 2009-06-11 13:27:13.0 SDN:P06::KSP3 Kilograms per cubic metre per second kg/m^3/s Unavailable 1 1 2009-06-11 13:27:13.0 accepted false SDN:P06::KGPH SDN:P06::KGPH 2017-03-17 14:45:02.0 SDN:P06::KGPH Kilograms per hour kg/h Unavailable 1 1 2017-03-17 14:45:02.0 accepted false SDN:P06::KMPS SDN:P06::KMPS 2009-06-11 13:23:32.0 SDN:P06::KMPS Kilograms per metre per second kg/m/s Unavailable 1 1 2009-06-11 13:23:32.0 accepted false SDN:P06::KMP2 SDN:P06::KMP2 2009-06-11 13:25:00.0 SDN:P06::KMP2 Kilograms per square metre kg/m^2 Unavailable 1 1 2009-06-11 13:25:00.0 accepted false SDN:P06::KSP2 SDN:P06::KSP2 2009-06-11 13:25:51.0 SDN:P06::KSP2 Kilograms per square metre per second kg/m^2/s Unavailable 1 1 2009-06-11 13:25:51.0 accepted false SDN:P06::KGS2 SDN:P06::KGS2 2009-07-06 21:24:54.0 SDN:P06::KGS2 Kilograms squared per second squared kg^2/s^2 Unavailable 1 1 2009-07-06 21:24:54.0 accepted false SDN:P06::ULKM SDN:P06::ULKM 1994-09-16 00:00:00.0 SDN:P06::ULKM Kilometres km Unavailable 1 1 1994-09-16 00:00:00.0 accepted false SDN:P06::KMDY SDN:P06::KMDY 2014-02-04 12:49:44.0 SDN:P06::KMDY Kilometres per day km/d A change in location of a distance of one thousand metres in an elapsed time of one day (86400 seconds). 2 2 2014-02-04 12:49:44.0 accepted false SDN:P06::KIPA SDN:P06::KIPA 2014-02-04 12:49:44.0 SDN:P06::KIPA Kilopascals kPa A force of one thousand Newtons per square metre. 2 2 2014-02-04 12:49:44.0 accepted false SDN:P06::UYKA SDN:P06::UYKA 2014-02-04 12:49:44.0 SDN:P06::UYKA Kiloyears before present kyr The length of time elapsed expressed as thousands of years between the event of interest and the year 1950 AD. 2 2 2014-02-04 12:49:44.0 accepted false SDN:P06::UKNT SDN:P06::UKNT 2000-12-28 12:25:11.0 SDN:P06::UKNT Knots (nautical miles per hour) Knots Unavailable 1 1 2000-12-28 12:25:11.0 accepted false SDN:P06::ULIT SDN:P06::ULIT 1996-11-13 00:00:00.0 SDN:P06::ULIT Litres l Unavailable 1 1 1996-11-13 00:00:00.0 accepted false SDN:P06::ULKG SDN:P06::ULKG 1997-02-07 00:00:00.0 SDN:P06::ULKG Litres per kilogram l/kg Unavailable 1 1 1997-02-07 00:00:00.0 accepted false SDN:P06::LPUM SDN:P06::LPUM 2014-06-24 12:09:26.0 SDN:P06::LPUM Litres per micromole l/umol The inverse of a molar concentration -
