Running on incorrect pressures will decrease fuel economy, it increases tyre wear and also degrades vehicle braking ability. Renault Symbol tire pressures should be checked at least once per month. How Often Should I Check My Renault Symbol Tire Pressures? p. 66.Renault Symbol Tire Pressure And Tire Size Comparison Tire Size National Institute of Standards and Technology. ^ NIST Special Publication 811 – Guide for the Use of the International System of Units (SI) (PDF).^ BS 350: Part 1: 1974 – Conversion factors and tables.^ An example of the use of Mpsi in mechanics for the elastic moduli of several materials.The tensile strength of steel may also be shown in MPa, or megapascal. For example, a tensile strength of a steel that can withstand 40,000 pounds of force per square inch may be expressed as 40,000 PSI or 40 KSI (with K being the for thousands of pounds). A metal’s yield strength and ultimate tensile strength values are expressed in tons per square inch, pounds per square inch or thousand pounds (KSI) per square inch. ^ "Tensile Strength of Steel and Other Metals".Archived from the original on August 1, 2011. ^ "Glossary of Industrial Air Cleaning Technology".Psychology Symbol Keyring Stainless Steel Psychoanalysis Greek Letter PSI. ^ IEEE Standard Letter Symbols for Units of Measurement (SI Units, Customary Inch-Pound Units, and Certain Other Units), IEEE Std 260.1™-2004 (Revision of IEEE Std 260.1-1993) Simple Stainless Steel Greek Letter PSI Symbol Silver Color Keychains Jewery.1000 kPa ≈ 145 lbf/in 2.Īpproximate conversions (rounded to some arbitrary number of digits, except when denoted by "≡") are shown in the following table.

Alternatively, place your insertion pointer where you need this symbol, then 03A8 and press Alt+X to get the PSI symbol. Main article: Orders of magnitude (pressure) Psi is the 23rd letter of the Greek alphabet and has a numeric value of 700. PSI Symbol Quick Guide To type the PSI Symbol on Word for Windows, simply press down the Alt key and type 936 using the numeric keypad, then let go of the Alt key. When gauge pressure is referenced to something other than ambient atmospheric pressure, then the units would be pounds per square inch differential ( psid). For example, a bicycle tire pumped up to 65 psig in a local atmospheric pressure at sea level (14.7 psi) will have a pressure of 79.7 psia (14.7 psi + 65 psi). The converse is pounds per square inch gauge ( psig), indicating that the pressure is relative to atmospheric pressure. Since atmospheric pressure at sea level is around 14.7 psi (101 kilopascals), this will be added to any pressure reading made in air at sea level. Pounds per square inch absolute ( psia) is used to make it clear that the pressure is relative to a vacuum rather than the ambient atmospheric pressure. In SI units, 1 psi is approximately equal to 6895 Pa. It is the pressure resulting from a force of one pound-force applied to an area of one square inch. The pound per square inch or, more accurately, pound-force per square inch (symbol: lbf/in 2 abbreviation: psi) is a unit of pressure or of stress based on avoirdupois units.
