Iyunithi elingana neenyawo ezingamashumi amabini
Iyunithi elinganayo yeemitha ezingamashumi amabini [1] okanye iTEU, ngumlinganiselo oqhelekileyo wobude ekuthuthweni kwezikhongozeli ze -ISO, kwaye ihambelana neenyawo ze-20 (malunga neemitha ezi-6) zizonke.
Imilinganiselo yangaphandle yesikhongozeli se-ISO zezi: 20 feet (6.1 m) ubude x 8 feet (2.4 m) ububanzi x 8.5 feet (2.6 m) ukuphakama. Umthamo wayo wangaphandle uyi-1,360 cubic feet, ilingana ne 38.51 m³, ngelixa umthamo wayo uzi-1,165.4 cubic feet, ilingana ne 33 m³. Obona bunzima besikhongozeli bumalunga nama-24,000 kg kodwa ngokususa ubunzima betare (okanye ubunzima obungenanto), umthwalo kwindawo yangaphakathi ungafikelela kuma-21,600. ikg.
Uninzi lwezikhongozeli ezinobude obuqhelekileyo be-20 kunye neenyawo ze-40 ngokulandelelanayo: i-20 foot (6.1 m) i-container ihambelana ne-1 TEU, i-40 foot (12.2 m) i-container ihambelana ne-2 TEU. Ukuchaza olu hlobo lokugqibela lwesikhongozeli, i akronim FEU, okanye "iyunithi elingana neenyawo ezingamashumi amane", ikwasetyenziswa.
Nangona ubude bezikhongozeli bunokwahluka, oku akunampembelelo kumlinganiselo we-TEU.
Lo mlinganiselo usetyenziselwa ukumisela umthamo wenqanawa ngokwenani leekhonteyina, inani leekhonteyina eziphathwayo kwizibuko kwixesha elithile, kwaye inokuba yiyunithi yokulinganisa ngokusekelwe kwiindleko zothutho.
