Tus raug ib qho yog K xwb, tsis yog qib K Qhov tsis meej pem tshwm sim vim yog lwm qhov ntsuas kub, qhov ntsuas Celsius (raws li qhov qub Centigrade nplai). Qhov ntsuas no tau muab los ntawm kev tau txais mercury-hauv-iav-iav tus pas ntsuas kub thiab kos cov dej khov thiab qhov chaw rau ntawm nws.
Puas yog kelvin lossis degree Kelvin?
Lub 13th CGPM (1967) tau txais lub npe kelvin (cim K) es tsis txhob "degree Kelvin" (cim ° K) thiab txhais cov chav ntsuas kub raws li hauv qab no: Lub kelvin, chav tsev ntawm qhov ntsuas kub ntawm qhov ntsuas kub, yog feem 1/273.16 ntawm qhov ntsuas kub ntawm qhov ntsuas kub ntawm triple point ntawm dej.
Vim li cas degree tsis sau nrog Kelvin?
A degree yog chav ntsuas ntsuas rau Celsius thiab Fahrenheit nplai, tab sis nws tsis siv nrog Kelvin nplai. Qhov no yog vim chav ntsuas ntsuas rau Kelvin nplai yog hu ua kelvin Ib qib ntawm cov ntsuas Celsius yog sib npaug rau ib kelvin ntawm Kelvin nplai.
Koj hais li cas Kelvin kub?
Kelvin (noun, “ KEHL-vin”)
Kev sib raug zoo ntawm Kelvin thiab degree Celsius yog dab tsi?
Tus ntsuas Celsius tam sim no txhais los ntawm ob qhov sib txawv: xoom xoom thiab peb npaug ntawm Vienna Standard Mean Dej Hiav Txwv Dej (VSMOW; tshwj xeeb tshaj yog cov dej huv). Raws li qhov no, kev sib raug zoo ntawm Celsius thiab Kelvin yog raws li nram no: TCelsius=TKelvin−273.15 T Celsius=T Kelvin − 273.15.
