SI yog tam sim no metric system ntawm kev ntsuas. Qhov yooj yim units hauv CGS yog centtimetre, gram, thib ob (yog li cov ntawv luv), thaum lub SI system siv ' meter ', kilogram thiab thib ob (xws li cov laus MKS qhov system ntawm units - Wikipedia).
Tib neeg kuj nug, metric SI system yog dab tsi?
Cov SI system , kuj hu ua metric system , yog siv thoob ntiaj teb. Muaj xya qhov yooj yim units hauv SI system 'meter' (m), kilogram (kg), qhov thib ob (s), kelvin (K), ampere (A), mole (mol), thiab candela (cd).
Tsis tas li ntawd, qhov sib txawv tseem ceeb ntawm SI units ntsuas qhov system thiab lus Askiv qhov kev ntsuas yog dab tsi? Feem ntau lub tebchaws siv Metric Qhov system , uas siv cov ntsuas ntsuas xws li meters thiab grams thiab ntxiv prefixes xws li kilo, milli thiab centi suav txiav txim ntawm qhov loj. Hauv Tebchaws Meskas, peb siv cov laus Imperial system , nyob qhov twg ntsuas hauv taw, ntiv tes thiab phaus.
Ntawm no, puas yog tag nrho SI units metric?
International System ntawm Chav tsev (Système International d'unités lossis SI ) yog tus qauv thoob ntiaj teb tam sim no ntsuas system thiab tseem yog qhov system feem ntau siv thoob ntiaj teb. Nws yog qhov txuas ntxiv ntawm Giorgi's MKSA system-nws lub hauv paus units yog ' meter ', kilogram, thib ob, ampere, kelvin, candela thiab mole.
Vim li cas lub metric system siv nyob rau hauv science?
Cov metric system yog qhov nyiam qhov system ntawm scientific units rau ntau qhov laj thawj: Feem ntau ntawm cov teb chaws hauv ntiaj teb no ntiav cov metric system ntawm kev ntsuas. Vim metric units yog decimal-raws li, lawv tau yooj yim hloov dua siab tshiab los ntawm kev txav tus decimal point.
