Iiyunithi zokulinganisa

Iiyunithi zomlinganiselo zezi izixhobo ezisetyenziselwa ukulinganisa izinto ezahlukeneyo, ukuya kuthi ga kumanani ngokwawo avumela ukubala ezo zinto zinokwahlulwa njengeeyunithi. Ayisiyiyo yonke into abantu abazimisele ukuyilinganisa enokwahlulwa ngeeyunithi, nditsho nokongeza ukubakho kwamaqhezu: kunyanzelekile kwiimeko ezithile ukwazisa iipateni zemilinganiselo eyahlukeneyo.

Ezi yunithi zincedisa amaxabiso esikali, kwaye ngokubanzi zenza igama elinye okanye amabini achazwe ekupheleni kwenani. Ulwazi malunga neeyunithi zemilinganiselo lwenza ukuba kuqondwe ukuba loluphi uhlobo lweyunithi esithetha ngalo. Nangona kunjalo, ngaphakathi komlinganiso wobungakanani kukho amabinzana ohlukeneyo, okwenza ukuba kube yimfuneko Inkqubo yokuguqula, apho ulwazi ngamanye amaxesha luthintelwa kwiingcali zesayensi ngalo mbandela.

Kungenxa yoko le nto, ngokubhekisele kuninzi loluntu, kuyinto eqhelekileyo ukuba iiyunithi zomlinganiso zinikwe kwindawo enye kuphela kwingingqi enye: kuyo nayiphi na imeko, Ukuphindaphindwa kwento enye, engenzi ezimbini ezahlukeneyo (iigrama, iimiligram, kunye neekhilogram ziyinxalenye yento efanayo). Xa umntu ongazi kangako malunga neeyunithi zomlinganiso esiya kwenye indawo, kuqhelekile kuye ukuba abenokudideka kubungakanani bezixa.

Nangona kunjalo, kuvunyelwene ukuba kungeniswe Inkqubo yamanye amazwe yeeyunithi ukuze umhlaba ube nendlela eyodwa yokulinganisa ubungakanani obuthile. Kwavunyelwana ke ngoko ukuba kwenziwe uluhlu lweeyunithi ezisixhenxe zomlinganiso: enye yobude, enye yobunzima, enye yexesha, enye yamandla ombane ngoku, enye yeqondo lobushushu le-thermodynamic, enye yobungakanani bezinto kunye nenye yokukhanya .

Imizekelo engamashumi amabini yeeyunithi zemilinganiselo iya kuchazwa apha, ibalaselisa ezo ziyinxalenye yenkqubo yamanye amazwe yeeyunithi. Kwezinye iimeko, ubudlelwane obumiselwe kunye namazwe aphesheya buya kukhankanywa.

1. Indlela engaphantsi (umlinganiso wobude, inkqubo yamazwe ngamazwe yeeyunithi)
2. Intshi (ubude bemilinganiselo, apho imitha enye ilingana nee-intshi ezingama-39.37)
3. Iyadi (umlinganiso wobude, apho imitha enye ilingana neeyure eziyi-1.0936)
4. Iinyawo (umlinganiso wobude, apho imitha enye imalunga neenyawo ezingama-3.2708)
5. Imayile (umlinganiso wobude, apho imitha enye ingama-0.00062 eemayile)
6. Ikhilogram (umlinganiso wobunzima, inkqubo yamazwe ngamazwe yeeyunithi)
7. ILibra (umlinganiso wobunzima, apho ikhilogram ingama-2.20462 eepawundi)
8. Ilitye (umlinganiso wobunzima, kunye nekhilogremu enye elingana nelitye elingu-0.157473)
9. Ounce (umlinganiso wobunzima, apho ikhilogram ingama-35.274 ii-ounces)
10. Isibini (umlinganiso wexesha, inkqubo yamazwe ngamazwe yeeyunithi)
11. Iilitha (umlinganiso wevolumu, oqhele ukusetyenziswa)
12. Isidanga esiphakathi (umlinganiso wekona)
13. IsiRadian (umlinganiso we-angle, apho i-1 centesimal degree is 0.015708 radians)
14. Igaloni yaseMelika (ubungakanani bomthamo, olingana ne-3.78541 yeelitha)
15. Amp (umlinganiso wangoku, inkqubo yamanye amazwe yeeyunithi)
16. UKelvin (Umlinganiso wobushushu we-thermodynamic, inkqubo yamazwe onke yeeyunithi)
17. Iidigri zeCelsius (umlinganiso weqondo lobushushu, oqikelelwa kukuthatyathwa nguKelvin - 273.15)
18. Izidanga zeFahrenheit (umlinganiso weqondo lobushushu, oqikelelwe ngumsebenzi [(uKelvin - 273.15) * 1.8] + 32)
19. Umlomo (umlinganiso wobungakanani bezinto, inkqubo yamanye amazwe yeeyunithi)
20. Ikhandlela (umlinganiso wokuqina okukhanyayo, inkqubo yamanye amazwe yeeyunithi)
