Ko te rahi e tohu ana ki te tawhiti rawa atu i waenga i nga tohu e rua i runga i te mata o te poi, ka inehia e nga papa whakarara e rua e pa ana ki te mata.Ko te rahi o te timatanga ko te diameter poroporo ingoa, ko te rahinga o te poroporo, ko te diameter o te poroporo.Ka whakatauhia te rahi o te poi ma te ine i te rereketanga o te diameter o te poi, koinei te rereketanga i waenga i te inenga diameter nui me te iti rawa.Mo te rota kua whakaritea he rereke te diameter o te rota, ko te rereketanga i waenga i te diameter toharite o te poi nui me te poi iti rawa o te rota.
Ko te sphericity, he rereke ranei mai i te ahua porowhita, e tohu ana ki te nui o te kotiti ketanga o te poi mai i te ahua porowhita pono (kaore i te porowhita).Ka inehia tenei ma te huri i te poi ki runga i te kaiwhakawhiti ahorangi me te kaha ine iti iho i te 4 karamu (0.14 oz).Ko te kauwhata polar ka puta ki te porowhita iti rawa atu ka taea, a ko te rereketanga i waenga i tenei porowhita porohita me te diameter porohita ingoa ko te rereketanga.
