Unugga dhererku waa unugga aasaasiga ah ee ay dadku isticmaalaan si ay u cabbiraan dhererka walxaha ku jira meel bannaan. Wadamo kala duwani waxay leeyihiin cutubyo dhererkoodu kala duwan yahay. Waxaa jira noocyo badan oo hababka beddelka unit dhererka ee adduunka, oo ay ku jiraan cutubyada dhererka Chinese dhaqanka, cutubyada dhererka heerka caalamiga ah, cutubyada dhererka Imperial, cutubyada dhererka xiddigiska, iwm In nolol maalmeedka, waxbarashada, iyo wax soo saarka ganacsiga iyo hawlgalka, diinta cutubyada dhererka lama kala saari karo. Hoos waxaa ku yaal liiska hababka beddelka ee u dhexeeya cutubyo kala duwan, iyagoo rajeynaya inay si fiican ku caawiyaan.
Nidaamka Caalamiga ah ee Unugyada, halbeegga caadiga ah ee dhererkiisu waa "mitir", oo ay u taagan tahay calaamadda "m". Cutubyadan dhererkoodu waa mitir.
Habka beddelka ee u dhexeeya cutubyada dhererka heerka caalamiga ah waa sida soo socota:
1 kilomitir/km=1000 mitir/m=10000 decimeter/dm=100000 sentimitir/cm=1000000 millimeter/mm
1 millimeter/mm=1000 micron/μm=1000000 nanometer/nm
Cutubyada dhaqanka Shiinaha ee dhererka waxaa ka mid ah mayl, cagaha, cagaha, iwm. Qaabka beddelidda waa sida soo socota:
1 mayl = 150 cagood = 500 mitir.
2 mayl = 1 kiiloomitir (1000 mitir)
1 = 10 cagood,
1 cagood = 3.33 mitir,
1 cagood = 3.33 desiimeter
Wadamo yar oo Yurub iyo Ameerika ah, oo u badan Boqortooyada Ingiriiska iyo Maraykanka, ayaa adeegsada cutubyo boqortooyo ah, markaa cutubyada dhererka ay isticmaalaan sidoo kale way kala duwan yihiin, oo u badan mayl, yard, cagood, iyo inji. Qaabka beddelka cutubyada dhererka boqortooyadu waa sida soo socota: Mile (mayl) 1 mayl = 1760 yards = 5280 cagood = 1.609344 kiiloomitir Yard (yard, yd) 1 yard = 3 cagood = 0.9144 mitir Fathom (f, fath, Fa, ftm) 1 fathom = 2 yard = 1.8288 mitir Hirarka (furlong) 1 hir = 220 yard = 201.17 mitir cag (cag, ft, jamacnimadu waa cagood) 1 cagood = 12 inches = 30.48 sentimeter Inch (inji, in) 1 inch = 2.54 inch
Xagga xiddigiska, "sanad-iftiin" waxaa caadi ahaan loo adeegsadaa unugga dhererka. Waa masaafada uu ifka ku safray meel aan bannaanayn hal sano gudaheed, sidaas darteed waxaa sidoo kale loo yaqaannaa sannad-iftiin.
Habka beddelka ee cutubyada dhererka xiddigiska waa sida soo socota:
1 sano iftiin=9.4653×10^12km
1 parsec = 3.2616 sano iftiin
1 unug astronomical≈149.6 milyan kilomitir
Cutubyada dhererka kale waxaa ka mid ah: mitir (Pm), megameter (Mm), kiiloomitir (km), decimeter (dm), sentimitir (cm), millimeter (mm), mitirka xariirta (dmm), sentimitir (cmm), mikromitir (μm) , nanometers (nm), picometers (pm), femtometers (fm), ammeters (am), iwm.
Xidhiidhkooda beddelka mitirku waa sida soo socota:
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
