The torr (symbol: Torr) is a unit of pressure based on an absolute scale, defined as exactly 1/760 of a standard atmosphere (101325 Pa). Thus one torr is exactly 101325/760 pascals (≈ 133.32 Pa). Historically, one torr was intended to be the same as one "millimeter of mercury", but subsequent redefinitions of the two units made them slightly different (by less than 0.000015%). The torr is not part of the International System of Units (SI). It is often combined with the metric prefix milli to na… Web25 rows · These are the conventions used in this book.

WebPressure is a normal stress, and hence has dimensions of force per unit area, or {ML -1 T -2 }. In the English system of units, pressure is expressed as "psi" or lbf/in 2 . In the Metric system of units, pressure is expressed as "pascals" or N/m 2 . Standard atmospheric pressure is 101.3 kPa (0.1013 MPa) or 14.69 psi. Pressure Terminology.
