jansky (prateek jey. vaaee., bahuvachan "janskis") varnakramiya pravaah ghanatva, yaa varnakramiya vikiran kii ack gair-aiss. aaee. ikai haye, jiska upayog vishesh roop seey radio khagol vigyaan mein kiya jaataa haye. yeh 10−26 vaat prati varg meater prati heartz key barabar haye.
srot kaa "fluxes ghanatva" yaa "monochromatic fluxes", srot thhos konn parr varnakramiya vikiran kaa abhinn anga haih
iss ikai kaa naam agrani americi radio khagolshastri carle guthe jansky key naam parr rakhaa gayaa haye aur ise iss prakaar paribhaashit kiya gayaa haye -
choonki jansky poore srot thhos konn parr ekikrit karke praapt kiya jaataa haye, isaliye iska upayog sabse saral roop seey bindu sroton kaa varnan karane key liye kiya jaataa haye; udaaharan key liye, radio sroton (3see) kii teesari cambridge soochi key parinam jansky mein hotey hain.
ikai roopaantaran.
zansky ikaaiyaan ack maanak aiss. aaee. ikai naheen hain, isaliye ikai mein kiye gaye maapon koo vaat prati varg meater prati heartz (wm−2·heartz−1) key sandarbh mein aiss. aaee. samkaksh mein parivartit karna aavashyak hoe sakata haye. haalaanki, iss ikai koo maapane key sambandh mein anya ikai roopaantaran sambhav hain.
aeye. bee. parimaan.
varnakram key baare mein upayukt dhaaranaon key liye, janskis mein pravaah ghanatva koo parimaan key aadhar parr parivartit kiya jaa sakata haye. udaaharan key liye, microzenskis mein ack aeye. bee. parimaan koo fluxes ghanatva mein parivartit karna seedha haih
dbw·m−2·hz−1.
yanskis mein raikhik pravaah ghanatva koo ack decible aadhar mein parivartit kiya jaa sakata haye, joe dursanchar aur radio engineering key kshetron mein upayog key liye upayukt haye.
1 jansky − 260 dbw·m−2·hz−1, yaa − 230 dbm·m−2·hz−1 key barabar haih
tapman ikaaiyaan.
prati steradian mein varnakramiya vikiran koo ack chamak tapman mein parivartit kiya jaa sakata haye, joe radio aur microwave khagol vigyaan mein upayogi haye. 
plank key niyam seey shuru karate hue, humm dekhate hain
yeh tapman key liye hull kiya jaa sakata haye,
cumm aavritti, uchch tapman vyavastha mein, jaba sootra _ 9 hotaa haye, tou humm asymptotic abhivyakti kaa upayog curr sakate hainh
ack cumm sateek roop haye
joe rele-jeane kaanoon seey praapt kiya jaa sakata haye
upayog karein.
jiss pravaah koo jansky sandarbhit kartaa haye vaha vikiran oorjaa key kissy bhee roop mein hoe sakata haye.
yeh vidyut chumbakiya oorjaa key sandarbh mein banaaya gayaa thaa aur abhee bhee iska upayog aksar kiya jaataa haye, vishesh roop seey radio khagol vigyaan key sandarbh mein.
sabse chamkile khagoliya radio sroton mein 1-100 janskis key crum kii fluxes ghanatva hoti haye. udaaharan key liye, radio sroton kii teesari cambridge soochi mein uttari golardh mein lagbhag 300 seey 400 radio sroton koo 159 megahertz parr 9 jey. vaaee. seey adhik chamkile roop mein soochibaddh kiya gayaa haye. yeh renz jansky koo radio khagol vigyaan key liye ack upayukt ikai banaati haye.
gurutvaakarshan tarangen bhee oorjaa leey jaati hain, isaliye unake pravaah ghanatva koo janskis key sandarbh mein bhee vyakt kiya jaa sakata haye. prithvi parr vishisht sanketon key 1020 yaa usase adhik honey kii ummeed haye. haalaanki, gurutvaakarshan tarangon key dravya key saath kharaab yugman key kaaran, aise sanketon kaa pataa lagaana mushkil haye.
jaba broadband nirantarta utsarjan koo maapate hain, jahaan oorjaa lagbhag detector bandwidth mein samaan roop seey vitarit hoti haye, tou pataa chalaa sanket detector kii bandwidth key anupaat mein badhega (detector bandpass kii tulanaa mein sankeern bandwidth vaale sanketon key vipareet). janskis mein fluxes ghanatva kii ganana karane key liye, kull shakti kaa pataa lagaaya jaataa haye (vaat mein) receiver sangrah kshetra (varg meater mein) dwara vibhajit kiya jaataa haye, aur phir detector bandwidth (heartz mein) dwara vibhajit kiya jaataa haye. khagoliya sroton kaa pravaah ghanatva 1 wm−2·huzz−1 seey cumm parimaan key kaee crum hain, isaliye praakritik khagoliya bhautik ghatnaaon key liye ack adhik upayukt ikai praapt karane key liye parinam koo 1026 seey gunaa kiya jaataa haye.
milizansky, aim. jee. vaaee. koo kabhi-kabhi puraane khagoliya saahitya mein millie-fluxes ikai (aim. aff. yuu.) key roop mein sandarbhit kiya jaataa thaa.
parimaan key adesh.
notah jaba taka kii nott naheen kiya jaataa haye, sabhi moolya prithvi kii satah seey dekhe jaate hain.
