Unit nke ogologo bụ nkeji bụ isi nke ndị mmadụ na-eji tụọ ogologo ihe dị na mbara igwe. Mba dị iche iche nwere nkeji dị iche iche nke ogologo. E nwere ọtụtụ ụdị nke ogologo unit akakabarede ụzọ n'ụwa, gụnyere omenala Chinese ogologo nkeji, mba ọkọlọtọ ogologo nkeji, Imperial ogologo nkeji, astronomical ogologo nkeji, wdg Na ndụ anyị kwa ụbọchị, ọmụmụ, na Enterprise mmepụta na ọrụ, ntughari nke ogologo nkeji enweghị ikewapụ. N'okpuru ebe a bụ ndepụta nke usoro ntụgharị n'etiti nkeji dị iche iche, na-atụ anya inyere gị aka nke ọma.
Na International System of Units, ọkọlọtọ ọkọlọtọ nke ogologo bụ "mita", nke akara "m" nọchiri anya ya. Nkeji ogologo ndị a niile bụ metrik.
Usoro ntụgharị n'etiti nkeji ogologo ọkọlọtọ mba ụwa bụ nke a:
1 kilomita / km = 1000 mita / m = 10000 decimeter / dm = 100000 centimeters / cm = 1000000 millimeters / mm
1 millimeter/mm=1000 micron/μm=1000000 nanometer/nm
Nkeji ogologo nke ndị China ọdịnala gụnyere kilomita, ụkwụ, ụkwụ, wdg. Usoro ntụgharị bụ nke a:
1 mile = 150 ụkwụ = 500 mita.
2 kilomita = 1 kilomita (1000 mita)
1 = 10 ụkwụ,
1 ụkwụ = 3.33 mita,
1 ụkwụ = 3.33 decimeter
Mba Europe na Amerịka ole na ole, tumadi United Kingdom na United States, na-eji nkeji nke alaeze ukwu, yabụ nkeji ogologo ha na-eji dịkwa iche, ọkachasị kilomita, yad, ụkwụ na sentimita. Usoro ntụgharị maka nkeji ogologo nke alaeze ukwu bụ nke a: Mile (mile) 1 mile = 1760 yards = 5280 feet = 1.609344 kilomita Yard (yard, yd) 1 yard = 3 feet = 0.9144 meters Fathom (f, fath, Fa, ftm) 1 fathom = 2 yards = 1.8288 mita Wave (furlong) 1 ife = 220 yards = 201.17 mita Ụkwụ (ụkwụ, ft, plural bụ ụkwụ) 1 ụkwụ = 12 sentimita asatọ = 30.48 centimeters Inch (inch, in) 1 inch = 2.54 centimeters
Na mbara igwe, a na-ejikarị "afọ ọkụ" dị ka nkeji ogologo. Ọ bụ ebe dị anya ọkụ na-aga n'ọnọdụ enweghị ohere n'ime otu afọ, yabụ a na-akpọkwa ya afọ ọkụ.
Usoro ntụgharị maka nkeji ogologo mbara igwe bụ nke a:
1 ìhè afọ=9.4653×10^12km
1 parsec = 3.2616 ìhè afọ
1 astronomical unit≈149.6 nde kilomita
Akụkụ ogologo ndị ọzọ gụnyere: mita (Pm), megameter (Mm), kilomita (km), decimeter (dm), centimita (cm), millimeter (mm), mita silk (dmm), centimeters (cmm), micrometers (μm) , nanometers (nm), picometers (pm), femtometers (fm), ammeters (am), wdg.
Mmekọrịta ntụgharị ha na mita bụ ndị a:
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
