Heoi, e tika ana ki te ao, me te whanaketanga o te wehenga ao o mahi, ko mooni ko te hanganga o te pūnaha ōrite o pauna me mehua.

ka mau tenei tukanga tino he wa roa, a ko tona hua he ahua o te ngātahitia i waenganui i nga kura pūtaiao nui o te ao, kua ia o nei kua takoha ki te hanga i te tahi mau ātetenga. I te pae hopea, ua faaite te aho whakamutunga i roto i te tau 1960, a ka tangohia rite vai teie mahana pūnaha SI ao.

Ko ano he acronym i takea mai i te parau French Système International me mārama kore noa tetahi kaiputaiao, engari ano hoki he tangata noa, puta i te akoranga o te kura nui. I tona matua, te pūnaha SI ko te kohinga tino nui o ngā waeine, me te ratou whakairoiro mau, me te. e kore e Ko tōna whakatamarikitanga tikanga e States katoa e kua hainatia te tūtohinga e tika ana, i ki te hoatu ake ratou ake pūnaha.

Kei te whakapono te reira e kore e taea te whiwhi tetahi o enei tawhā i te tahi atu, i.e. ia o enei wae he taha motuhake pera-ka karanga. I runga i a ratou, i te tikanga o te whakarea me te wehenga he pārōnaki kōwae putanga, me te tamahanahana. E tonu para āhuatanga o enei āhuatanga, me rangahau pūtaiao maha nui hoatu ara ki te hiahia mō ngā uara hou.

Kua ite etahi uauatanga pūnaha SI i roto i te ahupūngao e tika ana ki te rerekētanga i roto i te whakahua, me te kanohi kauwhata o te kōwae, he reira kahore ngaro e, mo te tauira, i waenganui i te Wīwī, me te tuhi Hainamana o te wā "manokaramu" nui rerekētanga nui.

I tēnei wā, ko te pūnaha SI, i runga i te ringa kotahi, ko te ahua o te taurangi o te inviolability o te ariā pūtaiao taketake, i runga i te tahi atu te ringa, he tonu rite hoki huringa hou, me te huringa.
