Custom Point Units
-
Hello Everyone!
Is there a way to add in our own point units?
I'd like to add in some that we use that aren't in the list.

Hi Ed,
Well... yes and no. What unit would you like to use?
The catch-all 'yes' is that you can deselect 'use units as suffix' in the text renderer for a point, then specify a string of your choosing in the suffix, which will then appear after the value as the units do.
The 'no' is that if you work in Ed-meters (which are defined as 567 meters, of course) and are trying to use the converting units feature to display a point being read in meters in Ed-meters, you cannot define this unit. If you really need Ed-meters in your application, you can modify the UnitUtil.java class to have your specific unit String defined against its component units such that a converting unit for "Ed-meter" would work to display all values for this point whose units are 'meters' as divided by 567 and displayed as Ed-meters (or however you specify the labeling)
The 'kind of' part of the answer is that if you're trying to use the converting units to get from a point read in Joules to kWh, you can specify kWh by breaking it into the base units and expressing their relationship, i.e. kW*h
SI prefixes for magnitude are understood, as are multiplication and division operators to specify complex units. We have discussed giving people the ability to add custom units into the converting units structure, but it hasn't been high enough on our priority list to include yet.

Xof1986, just to clarify, yes you can use standard units that aren't listed in the drop-down and combine units. See the documentation below that I have copied from the help link in Mango (the blue help icon) in particular the two links to SI and non-SI units. By combine I mean that you can write V*s or m³/s
You can specify a Unit for a point. Type in the symbol for the unit e.g. kg, L, mA, Hz, lb. Note that for some units there are multiple ways of entering the unit, e.g. for degrees celsius you can enter °C or Celsius, for ohms you can use Ω or Ohm. Also remember that there are sometimes multiple definitions of a unit, e.g. there are metric tonnes (t), short tons (ton_us) and long tons (ton_uk). You can use all SI prefixes on SI units, e.g. you can enter W for watt and also µW (microwatt), MW (megawatt) etc.
For SI Units see the list here here.
For NonSI Units see the list here.
Note that there are also some units internally defined in this system:btu - British thermal unit
thm - Thermal Unit (BTU * 100000)
psi - Pounds per square inch
rpm - Revolutions per minute
ppm - Part per million
ppb - Part per billion
There are also some aliases for common units defined here:
Celsius - °C
Fahrenheit - °F
The Displayed unit specifies which unit the renderer should convert to for display (if supported by the renderer). Input format is the same as for Unit.The Integral unit used in the display of statistic and specifies which unit the integrated total should be displayed in. Input format is the same as for Unit.

I was previously avoiding using the suffix since it is tied to the Property Template. I'll go ahead and fine tune the property templates moving instead of using the generic one that I had made.
Thanks as always guys!
Ed
