Type in unit symbols, abbreviations, or full names for units of length, area, mass, pressure, and other types. You can find metric conversion tables for SI units, as well as English units, currency, and other data. The unit is named after Blaise Pascal, the eminent French mathematician, physicist and philosopher.Ĭ provides an online conversion calculator for all types of measurement units. The pascal (symbol Pa) is the SI unit of pressure.It is equivalent to one newton per square metre. ![]() The definition of a pascal is as follows: The SI prefix "mega" represents a factor of Thus a reading of 30 psig on a tire gauge represents an absolute pressure of 44.7 psi. If a pressure gauge is calibrated to read zero in space, then at sea level on Earth it would read 14.7 psi. The compressive strength of 4000 psi concrete is approximately 11 MPa (1600 psi) at 3 days, approximately 18 MPa (2600 psi) at 7 days, approximately 25 MPa (3600 psi) at 14 days, approximately 26. Humans do not feel this pressure because internal pressure of liquid in their bodies matches the external pressure. At sea level, Earth's atmosphere actually exerts a pressure of 14.7 psi. By contrast, psia measures pressure relative to a vacuum (such as that in space). ![]() Heat Deflection Temperature fiber stress loading 264 psi (1.8 MPa) 110 ☏ (43 ☌) (7 days) (ASTM D-648) Water Absorption 0.60 (7 days, 24 hour immersion. MPa to psig, or enter any two units below: Enter two units to convert From: The hose range is compatible with No-Skive fittings series 48. You can do the reverse unit conversion from
