2024 Tus sau: Miles Stephen | [email protected]. Kawg hloov kho: 2023-12-15 23:36
s (thib ob) = s (lub sij hawm; base chav tsev ) S = siemens (kev coj ua) s ap = scruple (mass) sA = statampere (hluav taws xob tam sim no) sabin = ft^2 (chaw; derived chav tsev )
Tom qab ntawd, ib tug kuj yuav nug, dab tsi yog lub chav tsev sawv rau?
Lub xya SI base units , qho yog muaj xws li: Ntev - 'meter' (m) Lub Sijhawm - thib ob (s) Cov Khoom Siv - mole (mole) Hluav taws xob tam sim no - ampere (A)
Tsis tas li, hom kev ntsuas L yog dab tsi? Cov litre (British, Commonwealth, thiab BIPM spelling) los yog litre (American spelling) (SI cim L thiab l, lwm yam cim siv: ℓ) yog ib tug tsis yog-SI unit ntawm ntim . Nws yog sib npaug rau 1 cubic decimetre (dm3), 1,000 cubic centimeters (cm3) los yog 0.001 cubic meter.
Ntawm no, koj sau units li cas?
Cov cai dav dav rau Kev Ntsuas Cov Ntsiab Lus
- Ib txwm abbreviate units thaum qhia txog cov xov tooj.
- Tshwj tsis yog tau sau tseg, cov lus qhia thiab ntau qhov chaw yog luv luv tib yam.
- Ib txwm muab qhov chaw nruab nrab ntawm tus lej thiab chav tsev, piv txwv li, 203.65 m, 457 um.
Koj sau SI units li cas?
Hauv sau ntawv , npe SI units yeej ib txwm sau ua ntawv me. Txawm li cas los xij, cov cim ntawm units npe tom qab ib tug neeg yog capitalized (piv txwv li, ampere thiab A). Cov cim no tsis yog cov ntawv luv, yog li lub sijhawm tsis tas yuav tsum muaj.
