Iyunithi yobude yiyunithi esisiseko esetyenziswa ngabantu ukulinganisa ubude bezinto ezisesithubeni.Amazwe ahlukeneyo aneeyunithi ezahlukeneyo zobude.Kukho iintlobo ezininzi zeendlela zokuguqula iyunithi yobude kwihlabathi, kubandakanywa iiyunithi zobude zaseTshayina, iiyunithi zobude obuqhelekileyo bezizwe ngezizwe, iiyunithi zobude bobukhosi, iiyunithi zobude beenkwenkwezi, njl. Kubomi bethu bemihla ngemihla, isifundo, kunye nemveliso yeshishini kunye nokusebenza, ukuguqulwa kwe iiyunithi ubude azinakwahlulwa.Apha ngezantsi kukho uluhlu lweefomula zokuguqula phakathi kweeyunithi ezahlukeneyo, ngethemba lokukunceda ngcono.
Kwi-International System of Units, iyunithi esemgangathweni yobude "yimitha", emele isimboli "m".Ezi yunithi zobude zonke ziyimetric.
Ifomula yoguqulo phakathi kweeyunithi zobude bomgangatho wamazwe ngamazwe imi ngolu hlobo lulandelayo:
Ikhilomitha eyi-1/km=1000 yeemitha/m=10000 idecimeter/dm=100000 iisentimitha/cm=1000000 millimeters/mm
1 millimeter/mm=1000 micron/μm=1000000 nanometer/nm
Iiyunithi zesiShayina zobude zibandakanya iimayile, iinyawo, iinyawo, njl. njl. Ifomula yokuguqula imi ngolu hlobo lulandelayo:
Imayile enye = 150 iinyawo = 500 yeemitha.
Iimayile ezi-2 = ikhilomitha enye (1000 yeemitha)
1 = iinyawo ezili-10,
Unyawo olu-1 = 3.33 yeemitha,
1 unyawo = 3.33 idecimeters
Amazwe ambalwa aseYurophu naseMelika, ingakumbi iUnited Kingdom neUnited States, asebenzisa iiyunithi zobukhosi, ngoko ubude bawo abusebenzisayo bukwahlukile, ubukhulu becala iikhilomitha, iiyadi, iinyawo nee-intshi.Ifomula yokuguqula iiyunithi zobude bobukhosi ngolu hlobo lulandelayo: Imayile (imayile) 1 imayile = 1760 yeeyadi = 5280 yeemitha = 1.609344 iikhilomitha Iyadi (iyadi, yd) 1 iyadi = 3 iinyawo = 0.9144 iimitha Fathom (f, fath, Fa, ftm) Ifathom eyi-1 = iiyadi ezi-2 = 1.8288 iimitha Amaza amaza (ubude) 1 iliza = 220 yeeyadi = 201.17 yeemitha Unyawo (unyawo, ft, isininzi ziinyawo) 1 unyawo = 12 intshi = 30.48 iisentimitha I-intshi (intshi, ngaphakathi) 1 intshi = 2.54
Kwi-astronomy, "unyaka wokukhanya" usetyenziswa ngokuqhelekileyo njengeyunithi yobude.Ngumgama ohanjwa kukukhanya kwimo yevacuum ngonyaka omnye, ngoko ikwabizwa ngokuba ngunyaka wokukhanya.
Ifomula yokuguqula yeeyunithi zobude be-astronomi ngolu hlobo lulandelayo:
1 unyaka ukukhanya=9.4653×10^12km
I-1 parsec = 3.2616 iminyaka yokukhanya
Iyunithi e-1 yeenkwenkwezi≈149.6 yezigidi zeekhilomitha
Ezinye iiyunithi zobude ziquka: imitha (i-Pm), i-megameter (Mm), ikhilomitha (km), i-decimeter (dm), i-centimeter (cm), i-millimeter (mm), i-silk meter (dmm), iisentimitha (cmm), ii-micrometers (μm) , iinanometers (nm), iipicometers (pm), femtometers (fm), iiammeters (am), njl.
Ubudlelwane babo boguqulo kunye nemitha buhamba ngolu hlobo lulandelayo:
1PM =1×10^15m
1Gm =1×10^9m
1Mm =1×10^6m
1km=1×10^3m
1dm=1×10^(-1)m
1cm=1×10^(-2)m
1mm=1×10^(-3)m
1dmm =1×10^(-4)m
1cm =1×10^(-5)m
1μm=1×10^(-6)m
1nm =1×10^(-9)m
1pm=1×10^(-12)m
1fm=1×10^(-15)m
1am=1×10^(-18)m
