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 o ka lōʻihi o 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
