Un esempio è la pressione dell'aria all'interno di uno <a href="/wiki/Pneumatico" title="Pneumatico">pneumatico</a> d'<a href="/wiki/Automobile" title="Automobile">automobile</a>, ad esempio una pressione di "2,2 atmosfere" significa 2,2 atmosfere oltre la <a href="/wiki/Pressione_atmosferica" title="Pressione atmosferica">pressione atmosferica</a>, ovvero la pressione assoluta è pari a 3,2 atmosfere. </p><p>La pressione relativa inoltre non può scendere al di sotto di un valore negativo, fissato pari a −101.325 Pa. Ciò è giustificato dal fatto che sommando la pressione atmosferica (101.325 Pa) si ottiene una pressione assoluta uguale a zero, il cosiddetto "vuoto assoluto", al di sotto del quale non si può andare per motivi fisici. </p><p>Con la diffusione dell'uso del Sistema Internazionale anche in ambito meteorologico, la pressione atmosferica si misura in centinaia di Pascal (o ettopascal, abbreviato con hPa). Si ha: 1.013,25 <a href="/wiki/Millibar" class="mw-redirect" title="Millibar">millibar</a> = 101.325 Pa = 1.013,25 hPa. </p> <div class="mw-heading mw-heading3"><h3 id="Unità_di_misura_anglosassoni"><span id="Unit.C3.A0_di_misura_anglosassoni"></span>Unità di misura anglosassoni</h3><span class="mw-editsection"><span class="mw-editsection-bracket">[</span><a href="/w/index.php?title=Pressione&veaction=edit&section=6" title="Modifica la sezione Unità di misura anglosassoni" class="mw-editsection-visualeditor"><span>modifica</span></a><span class="mw-editsection-divider"> | </span><a href="/w/index.php?title=Pressione&action=edit&section=6" title="Edit section's source code: Unità di misura anglosassoni"><span>modifica wikitesto</span></a><span class="mw-editsection-bracket">]</span></span></div> <p>Un'ulteriore unità di misura (ancora in uso in alcune parti del mondo) è il <a href="/wiki/Psi_(unit%C3%A0_di_misura)" title="Psi (unità di misura)">psi</a> (<i>Pounds per Square Inch</i>), o <a href="/wiki/Libbra_forza" title="Libbra forza">libbra forza</a> per <a href="/wiki/Pollice_quadro" title="Pollice quadro">pollice quadro</a>. </p> <div class="mw-heading mw-heading3"><h3 id="Unità_manometriche"><span id="Unit.C3.A0_manometriche"></span>Unità manometriche</h3><span class="mw-editsection"><span class="mw-editsection-bracket">[</span><a href="/w/index.php?title=Pressione&veaction=edit&section=7" title="Modifica la sezione Unità manometriche" class="mw-editsection-visualeditor"><span>modifica</span></a><span class="mw-editsection-divider"> | </span><a href="/w/index.php?title=Pressione&action=edit&section=7" title="Edit section's source code: Unità manometriche"><span>modifica wikitesto</span></a><span class="mw-editsection-bracket">]</span></span></div> <p>Obsolete unità manometriche di pressione, come i <a href="/w/index.php?title=Pollici_d%27acqua&action=edit&redlink=1" class="new" title="Pollici d'acqua (la pagina non esiste)">pollici d'acqua</a> o i <a href="/wiki/Millimetri_di_mercurio" class="mw-redirect" title="Millimetri di mercurio">millimetri di mercurio</a>, si basano sulla pressione esercitata dal <a href="/wiki/Forza_peso" title="Forza peso">peso</a> di qualche <a href="/wiki/Fluido" title="Fluido">fluido</a> tipo, sotto una <a href="/wiki/Gravit%C3%A0" class="mw-redirect" title="Gravità">gravità</a> tipo.
