Temperature conversion Can be achieved by using the following formula:
° F = ( ° C x 1.8) + 32 ° C = ( ° F - 32) 1.8
Additional information Atmosphere - (standard reference) A.N.R. (Atmosphère Normale de Référence) ISO R558. This is the agreed atmosphere to control specification values and test results, as given in ISO R554. Pneumatic fluid power uses 1013 mbar, 20 ° C, 65% RH (ISO R554). Compressor and pneumatic tool industries prefer 1000 mbar, 20 ° C, 65% RH (ISO 2787). Aerospace, Petroleum and British Gas Industries prefer 1013 mbar, 15 ° C, Dry (ISO 2533 and ISO 5024). Fluid power users are sometimes confused by N m ³ . This is not Newton-metres ³ but refers to meters ³ A N R, i.e. a volume of air measured against the standard or normal atmosphere reference. The equivalent imperial term is S.C.F. (Standard Cubic Feet).

Litre The symbol l is being superceded by L to avoid confusion with 1 (one). 1 L = 1 dm³.

bar 1 bar = 100 kPa = 100 kN/m ² .
kg/cm² This unit is still used in some areas. The conversions are as follows: 1 kg/cm ² = 0.980665 bar = 0.967841 atmos = 14.2233 psi
