  2. Muab nws tawm (tawm tag nrho units hauv cov lus teb)
  3. Ncua tseg units uas yog ob sab saum toj thiab hauv qab.

Ib yam li ntawd, tib neeg nug, koj yuav hloov cov qauv li cas?

uas yog qhov nws txhais tau tias rau ib txheej ntawm cov ntaub ntawv yuav tsum nyob rau hauv txheem units . Standard units yog dimensionless. Yog tus thawj daim ntawv muaj units , tus thawj SD muaj tib yam units . Hloov ua lwm yam a ntsuas rau txheem units , peb faib cov ntsuas (rho tawm qhov txhais tau) los ntawm SD, uas tshem tawm qhov qub units.

Dab tsi yog cov units ntawm kev ntsuas? SI system, tseem hu ua metric system, yog siv thoob ntiaj teb. Muaj xya qhov yooj yim units Hauv SI system: lub ntsuas (m), kilogram (kg), qhov thib ob (s), kelvin (K), ampere (A), mole (mol), thiab candela (cd).
