Juyin Psi zuwa MPa, psi shine naúrar matsa lamba, wanda aka ayyana azaman fam kowane murabba'in inch, 145psi=1MPa, PSI ana kiranta Pound sper square inch a turance.P shine fam, S murabba'i ne, kuma ni inci ne.Mayar da duk raka'o'in zuwa raka'o'in ma'auni abin da ake samu:
1 bar≈14.5psi;1psi=6.895kPa=0.06895bar

A kasar Sin, gabaɗaya muna kwatanta matsi na iskar gas a cikin "kg" (maimakon "jin"), kuma sashin jiki shine "kg/cm^2".Kilogram na matsa lamba ɗaya yana nufin cewa kilogiram ɗaya na ƙarfi yana aiki akan santimita murabba'i ɗaya.
Naúrar da aka saba amfani da ita a ƙasashen waje ita ce “Psi”, kuma ƙayyadaddun naúrar ita ce “lb/in2”, wanda shine “laba kowace inci murabba’i”.Wannan rukunin yana kama da ma'aunin zafin jiki na Fahrenheit (F).
Bugu da kari, akwai Pa (Pascal, daya Newton aiki a kan murabba'in mita daya), KPa, Mpa, Bar, millimeter ruwa shafi, millimeter mercury column da sauran matsa lamba raka'a.
1 mashaya (bar) = 0.1 MPa (MPa) = 100 kilopascal (KPa) = 1.0197 kg/cm²

Akwai nau'ikan tsarin bawul guda biyu: ɗayan shine tsarin "matsa lamba mara izini" wanda Jamus ke wakilta (ciki har da ƙasata) bisa la'akari da matsi na aiki da aka yarda a zafin jiki (digiri 100 a ƙasata da digiri 120 a Jamus).Ɗaya shine "tsarin zafin jiki da matsa lamba" wanda Amurka ke wakilta kuma yana wakilta ta matsi na aiki da aka yarda a wani zafin jiki.
A cikin tsarin zafin jiki da matsa lamba na Amurka, ban da 150LB, wanda ya dogara da digiri 260, duk sauran matakan suna dogara ne akan digiri 454.
Danniya da aka yarda da aji na 150-psi (150psi = 1MPa) No. 25 carbon karfe bawul ne 1MPa a 260 digiri, da kuma yarda danniya a dakin zafin jiki ne yafi girma fiye da 1MPa, game da 2.0MPa.
Sabili da haka, gabaɗaya magana, matakin matsa lamba na ƙididdiga wanda yayi daidai da ma'auni na Amurka 150LB shine 2.0MPa, matakin matsa lamba na ƙima wanda yayi daidai da 300LB shine 5.0MPa, da sauransu.
Don haka, matsa lamba na ƙididdiga da zafin jiki da ma'aunin matsi ba za a iya jujjuya su ba bisa ga tsarin jujjuyawar matsa lamba.
