In MathCAD, the evaluation toolbar has custom in/post/pre/treefix operators. Of particular interest to me at this moment is the postfix operator ([Ctrl][Shift]X in MathCAD). I need to define Decibels (dB ) which is a scale and not a proper unit. Thank you Edited by user 13 April 2018 00:03:37(UTC)

Yes. Interesting, Valery never showed me that was of doing decibles in MathCAD. Tom Gutmann showed me how to properly create a "new" unit name with the postfix operator, and there is another thread for electrical Edited by user 07 November 2012 03:57:40(UTC)

SS-3532 I can think of a few scale units... dB, pH, psia/psig psia/psig is currently intriging for me because the scaling factor is calculated from a function. Considering SMath works in absolute scales, psi should be renamed psia or psi(a). In the one comversation i could find on this topic, https://en.smath.info/fo...ssible-improvement.aspx, Randovan's example is that pressure conversion scale is @ 14.7 psi. This is not always the case. I'm looking at a problem concerning compressed air in Denver where the conversion scale is 12.3. My function works correctly but is based off of elevation and I cannot properly define the unit. I'll post my example when I get to a computer Posting sheet that was used in the bug report Originally Posted by: ElSid BUG.smz (4kb) downloaded 32 time(s).

Will the CTRL+K allow us to define the scale of dB? Inspired from Originally Posted by: Davide Carpi However, yes, can be done even this (CTRL+K to add the backslash)
