Amayunithi asetshenziswa kakhulu kanye nokuguqulwa kwama-casters ezimboni

Amayunithi amabili avame ukusetshenziswa kuma-casters ezimboni:
● Amayunithi obude: i-intshi eyodwa ilingana nobude obuphelele bezikhwebu ezintathu zebhali;
● Iyunithi yesisindo: iphawundi elilodwa lilingana nesisindo esiphindwe izikhathi ezingu-7,000 sebhali elithathwe phakathi nendlebe;

Ngokuphathelene nobude kumayunithi asebukhosini: Ngemva kuka-1959, i-intshi ohlelweni lwaseMelika kanye ne-intshi ohlelweni lwaseBrithani kwalinganiswa kwaba ngu-25.4 mm ukuze kusetshenziswe ngokwesayensi nangokwezentengiselwano, kodwa uhlelo lwaseMelika lwagcina "i-intshi elinganisiwe" esetshenziswa ezilinganisweni ezihlukile kancane.
I-intshi eli-1 = amasentimitha angu-2.54 (cm)
Inyawo eli-1 = amayintshi angu-12 = 30.48 cm
Iyadi eli-1 = amafidi ama-3 = amasentimitha angu-91.44 (cm)
● Imayela eli-1 = amayadi angu-1760 = amakhilomitha angu-1.609344 (km)

Ukuguqulwa kwesisindo seyunithi yesiNgisi:
● Uhlamvu olulodwa = amamiligremu angu-64.8
Idrakhimu eli-1 = 1/16 ounce = 1.77 amagremu
I-ounce eli-1 = 1/16 pound = 28.3 grams
● Iphawundi eli-1 = okusanhlamvu okungu-7000 = amagremu angu-454
Itshe eli-1 = amakhilogremu angu-14 = amakhilogremu angu-6.35
● Ilitha eli-1 = amatshe ama-2 = amakhilogremu angu-28 = amakhilogremu angu-12.7
● Ilitha eli-1 = amalitha ama-4 = amakhilogremu angu-112 = amakhilogremu angu-50.8
Ithani eli-1 = amalitha angu-20 = amakhilogremu angu-2240 = amakhilogremu angu-1016

Ukuguqulwa kwamayunithi kudinga inqubo ejwayelekile, uma sibona okuningi, sibala okuningi, kungakhathaliseki ukuthi abantu bakunikeza amayunithi asekhaya noma angaphandle, ungawaguqula ngokushesha abe amayunithi owajwayele. Uma uhilelekile embonini yama-casters ezimboni, uzovame ukuhlangana namasentimitha namasentimitha, amamilimitha phakathi kokuguqulwa; kanye nezinhlobo zamayunithi phakathi kokuguqulwa emsebenzini wansuku zonke ezincane kakhulu.
