Mayunitsi omwe amagwiritsidwa ntchito kwambiri komanso osinthira makina opangira mafakitale

Magawo awiri omwe amagwiritsidwa ntchito kwambiri pakupanga ma casters amakampani:
● Magawo a kutalika: inchi imodzi ikufanana ndi kutalika konse kwa ngala zitatu za barele;
● Unit of weight: paundi imodzi ndi yofanana ndi kulemera kwa barele wotengedwa pakati pa khutu ka 7,000;

Ponena za kutalika kwa mayunitsi achifumu: Pambuyo pa 1959, inchi mu dongosolo lachifumu la America ndi inchi mu dongosolo la Britain zinayikidwa muyeso wa 25.4 mm kuti zigwiritsidwe ntchito mwasayansi ndi zamalonda, koma dongosolo la America linasunga "inchi yoyezedwa" yomwe imagwiritsidwa ntchito mu miyeso yosiyana pang'ono.
Inchi imodzi = masentimita 2.54 (cm)
Phazi limodzi = mainchesi 12 = 30.48 cm
Yadi imodzi = mapazi atatu = masentimita 91.44 (cm)
● Makilomita 1 = mayadi 1760 = makilomita 1.609344 (km)

Kusintha kwa kulemera kwa mayunitsi a Chingerezi:
● Njere imodzi = 64.8 milligrams
Drakima imodzi = 1/16 ounce = 1.77 magalamu
1 ounce = 1/16 paundi = 28.3 magalamu
● Paundi imodzi = tirigu 7000 = magalamu 454
Mwala umodzi = mapaundi 14 = makilogalamu 6.35
● Lita imodzi = miyala iwiri = mapaundi 28 = makilogalamu 12.7
● Lita imodzi = malita anayi = mapaundi 112 = makilogalamu 50.8
Toni imodzi = malita 20 = mapaundi 2240 = makilogalamu 1016

Kusintha mayunitsi kumafuna njira yodziwika bwino, tikawona zambiri, kuwerengera zambiri, kaya anthu akukupatsani mayunitsi am'nyumba kapena akunja, mutha kusintha mwachangu kukhala mayunitsi omwe mumadziwa bwino. Ngati mukuchita nawo mafakitale opanga ma casters amakampani, nthawi zambiri mumakumana ndi mainchesi ndi masentimita, mamilimita pakati pa kusintha; ndi mitundu ya mayunitsi pakati pa kusintha mu ntchito ya tsiku ndi tsiku yocheperako.
