Mayunitsi omwe amagwiritsidwa ntchito nthawi zambiri komanso osinthika amakampani opanga mafakitale

Magawo awiri omwe amagwiritsidwa ntchito kwambiri popanga mafakitale:
● Utali wa mayunitsi: inchi imodzi ikufanana ndi ngala zitatu zonse za balere;
● Chigawo cha kulemera kwake: kilogalamu imodzi ndi yofanana ndi kulemera kwa 7,000 kwa balere wotengedwa pakati pa ngala;

Ponena za kutalika kwa mayunitsi achifumu: Pambuyo pa 1959, inchi mu dongosolo lachifumu la America ndi inchi mu dongosolo la Britain zidasinthidwa kukhala 25.4 mm kuti zigwiritsidwe ntchito pazasayansi ndi zamalonda, koma dongosolo la America lidasungabe "inchi yoyezera" yomwe imagwiritsidwa ntchito mumiyeso yosiyana pang'ono.
1 inchi = 2.54 masentimita (cm)
1 phazi = mainchesi 12 = 30.48 cm
1 bwalo = 3 mapazi = 91.44 masentimita (cm)
● 1 mile = 1760 mayadi = 1.609344 kilomita (km)

Kusintha kulemera kwa unit English:
● 1 njere = 64.8 milligrams
1 drachm = 1/16 ounce = 1.77 magalamu
1 ounce = 1/16 pounds = 28.3 magalamu
● 1 pounds = 7000 njere = 454 magalamu
1 mwala = mapaundi 14 = 6.35 kilogalamu
● 1 quart = miyala 2 = mapaundi 28 = 12.7 kilograms
● 1 quart = 4 quarts = 112 pounds = 50.8 kilograms
1 toni = 20 quarts = 2240 pounds = 1016 kilograms

Kutembenuka kwa mayunitsi kumafuna njira yodziwika bwino, tikawona zambiri, werengerani zambiri, kaya anthu amakupatsani mayunitsi apanyumba kapena mayunitsi akunja, mutha kusintha mwachangu kukhala mayunitsi omwe mumawadziwa bwino. Ngati mukuchita nawo makampani opanga mafakitale, nthawi zambiri mumakumana ndi mainchesi ndi ma centimita, mamilimita pakati pa kutembenuka; ndi mitundu ya mayunitsi pakati pa kutembenuka mu ntchito ya tsiku ndi tsiku yocheperako.
