ʻO ka ʻāpana o ka lōʻihi ka ʻāpana kumu i hoʻohana ʻia e nā kānaka e ana i ka lōʻihi o nā mea ma ke ākea.Loaʻa i nā ʻāina like ʻole nā ʻāpana o ka lōʻihi.Nui nā ʻano o nā ʻano hoʻololi ʻana o ka lōʻihi ma ka honua, me nā ʻāpana lōʻihi Kina, nā ʻāpana lōʻihi maʻamau, nā ʻāpana lōʻihi imperial, nā ʻāpana lōʻihi astronomical, etc. ʻAʻole hiki ke hoʻokaʻawale ʻia nā ʻāpana lōʻihi.Aia ma lalo kahi papa inoa o nā ʻano hoʻololi ma waena o nā ʻāpana like ʻole, me ka manaʻo e kōkua maikaʻi iā ʻoe.
Ma ka International System of Units, ʻo ka ʻāpana maʻamau o ka lōʻihi he "mika", i hōʻike ʻia e ka hōʻailona "m".He metric kēia mau ʻāpana lōʻihi.
ʻO ke kumu hoʻololi ma waena o nā ʻāpana lōʻihi maʻamau maʻamau penei:
1 kilomika/km=1000 mika/m=10000 decimeter/dm=100000 kenimika/cm=1000000 millimeters/mm
1 millimeter/mm=1000 micron/μm=1000000 nanometer/nm
He mau mile, kapuaʻi, kapuaʻi, a pēlā aku ka lōʻihi o ka lōʻihi o Kina. Penei ke kumu hoʻololi:
1 mile = 150 kapuai = 500 mika.
2 mile = 1 kilomika (1000 mika)
1 = 10 kapuaʻi,
1 kapuai = 3.33 mika,
1 kapuai = 3.33 decimeters
ʻO kekahi mau ʻāina ʻEulopa a me ʻAmelika, ʻo ia hoʻi ʻo United Kingdom a me ʻAmelika Hui Pū ʻIa, hoʻohana i nā ʻāpana imperial, no laila ʻokoʻa nā ʻāpana lōʻihi a lākou e hoʻohana ai, ʻo ka hapa nui o nā mile, nā iwilei, nā wāwae, a me nā iniha.Penei ka hoʻololi ʻana no nā ʻāpana lōʻihi imperial: Mile (mile) 1 mile = 1760 iwilei = 5280 kapuaʻi = 1.609344 kilomita Yard (yard, yd) 1 iwilei = 3 kapuaʻi = 0.9144 mika Fathom (f, fath, Fa, ftm) 1 anana = 2 iwilei = 1.8288 mika Ka nalu (furlong) 1 nalu = 220 iwilei = 201.17 mika Kapuai (kapuai, ft, ka nui he wawae) 1 kapuai = 12 iniha = 30.48 kenimika Iniha (inihi, in) 1 iniha = 2.54 keneta
Ma ka astronomy, hoʻohana mau ʻia ka "makahiki-mālamalama" ma ke ʻano he ʻāpana o ka lōʻihi.ʻO ia ka mamao i hele ʻia e ka mālamalama i loko o ka moku maloʻo i hoʻokahi makahiki, no laila ua kapa ʻia ʻo ia he makahiki māmā.
ʻO ke kumu hoʻololi no nā ʻāpana lōʻihi astronomical penei:
1 makahiki māmā=9.4653×10^12km
1 parsec = 3.2616 mau makahiki māmā
1 ʻāpana hōkū≈149.6 miliona kilomika
ʻO nā ʻāpana lōʻihi ʻē aʻe: mika (Pm), megameter (Mm), kilomika (km), decimeter (dm), kenimika (cm), millimeter (mm), mika silika (dmm), Kenimika (cmm), micrometers (μm) , nanometer (nm), picometers (pm), femtometers (fm), ammeters (am), etc.
ʻO kā lākou pilina hoʻololi me nā mika penei:
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
1cmm =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
