Editing Pascal (unit) (section)

== Definition ==
The pascal can be expressed using [[SI derived unit]]s, or alternatively solely [[SI base unit]]s, as:
: <math>{\rm 1~Pa = 1~N/m^2 =  1~kg/(m {\cdot} s^2) = 1~J/m^3 }</math>
where N is the [[Newton (unit)|newton]], m is the [[metre]], kg is the [[kilogram]], s is the [[second]], and J is the [[joule]].<ref>[http://www.bipm.org/en/si/si_brochure/chapter2/2-2/table3.html Table 3 (Section 2.2.2)]. {{webarchive|url=https://web.archive.org/web/20070618123613/http://www.bipm.org/en/si/si_brochure/chapter2/2-2/table3.html |date=18 June 2007 }}.

One pascal is the pressure exerted by a force of one newton perpendicularly upon an area of one square metre.
