Convert Process Units

Instrumentation Engineer enables Users to convert process units to another unit in the Datasheet Data Entry window.
A User can convert process units by right-clicking on any ProcessData table field (cells mapped to a ProcessData DB field) that contains a Pressure, Flow, Density, Temperature, Viscosity or Level value, or on any cell within the Datasheet Edit window mapped to such fields.
Note: The selected field must already contain valid numeric data along with a Process Unit recognized by AVEVA Instrumentation.
Right-click on such a field to display the following menu:
The Change Process Units sub-menu includes all the supported units for that process and enables you to change from one unit type to another unit type without changing the value. For example: 64°C to 64°F.
The Convert Units sub-menu includes all the supported units for that process type. The example below shows the sub-menu for a Temperature field:
To convert the selected field to a new unit and change the value to reflect this, click on the required unit from the sub-menu.
Conversion Prefixes
AVEVA Instrumentation uses a smart algorithm to recognize SI unit prefixes automatically as follows:
|
Si Prefix |
Name |
Power |
|
y |
yocto |
-24 |
|
z |
zepto |
-21 |
|
a |
atto |
-18 |
|
f |
femto |
-15 |
|
p |
pico |
-12 |
|
n |
nano |
-9 |
|
u |
micro |
-6 |
|
m |
milli |
-3 |
|
c |
centi |
-2 |
|
d |
deci |
-1 |
|
h |
hecto |
2 |
|
k |
kilo |
3 |
|
M |
mega |
6 |
|
G |
giga |
9 |
|
T |
tera |
12 |
|
P |
peta |
15 |
|
E |
exa |
18 |
|
Z |
zetts |
21 |
|
Y |
yotto |
24 |
Notes: For the conversion to be successful, these Si prefixes must be used with their correct case. e.g "KPa" will not be recognized. It should be "kPa".
By default, AVEVA Instrumentation is configured as follows:
- Absolute Zero = -273.15
- 1 Atmosphere = 101325
