The EcoStruxure Building Operation software supports both the SI metric system and the US Customary System for units of measurement.

There are four optional ways to display units:

  • As MS Windows

  • As configured in object

  • International System of Units (Metric)

  • United States Customary Units (US)

For example, the temperature 42,82 °C is stored in the EcoStruxure Building Operation software. A WorkStation on an operating system with the US Customary System converts the temperature and displays it as 109.08 °F.

As MS Windows

By default, values are converted into the unit given by the regional settings of the operating system.

As configured in object

Units displayed as configured in the object means that no conversion is done. The unit the user selected when creating, for example, a trend log is displayed regardless of regional settings. When this option is selected, the unit conversion exceptions feature is disabled.

International System of Units (Metric)

Values displayed in International System of Units means that the values are converted into metric unit regardless of the unit the object was given when created.

United States Customary Units (US)

Values displayed in United States Customary Units means that the values are converted into US unit regardless of the unit the object was given when created.

When you select a different unit system, the values are converted immediately.

Values are not converted in the following WorkStation screens:

  • Alarms and trend logs in wizards

  • Customized alarm views

  • Alarm and trend log properties panes

Delta Temperature Conversion

Hinweis

  • The EcoStruxure Building Operation software converts the unit of a variable independent of its context. To correctly convert a delta temperature, the unit of the delta value must belong to the unit category Temperature Diff.

The conversion between ​Celsius and Fahrenheit or ​Fahrenheit and Kelvin is not a simple ​coefficient (multiplier) like other unit categories as for example length, pressure, currency, and Energy. Due to the conversion formula when for example converting an absolute ​Fahrenheit temperature to Celsius​, T​°F=T​°C x 9/5 + 32, ​ you have both a multiplier and an offset to consider. To correctly convert a delta temperature from ​​Fahrenheit to ​Celsius​ you have to use the formula ΔT°F = 9/5 ΔT°C.
