Unit Conversion is used to transform telemetry values into a common measurement standard. During this process, the original source data remains unchanged, while the converted value is created as a new Virtual Tag that can be used throughout the platform.
Why Use Unit Conversion?
Devices may report the same type of data using different measurement units. Unit Conversion standardizes these values, allowing dashboards, reports, and alarm rules to work with consistent data.
A source telemetry value is selected, the target measurement unit is defined, and the converted result is stored as a new Virtual Tag. The original data remains unchanged while the converted value becomes available across the platform.

Supported Data Sources
Unit Conversion is not limited to telemetry values. Different data sources can be combined within the same conversion process.
Source values can be selected from telemetry, attributes, or constant values. This allows live sensor data and fixed coefficients to be used together within the same calculation.

Common Conversion Scenarios
1
Energy
Convert between common energy units such as W, kW, Wh and kWh.
2
Temperature
Normalize temperature values from different sources into a common unit.
3
Volume
Standardize volume measurements such as liters and cubic meters.
Usage Scenarios
Standardized values can be reused throughout the platform, ensuring consistent analysis and reporting regardless of the original data source.
Converted values can be displayed in dashboards, charts, and reports alongside other telemetry values using the same measurement standard.
DashboardsChartsReports
Virtual Tags created through Unit Conversion can be used in alarm rules, allowing thresholds to be evaluated using standardized values.
AlarmsRulesMonitoring
Keeping similar data in a single measurement unit improves dashboard consistency, reporting accuracy, and overall system management.

Recommendations
Use Standard Measurement Units
Whenever possible, use a single measurement unit for the same type of data. This improves the consistency of dashboards, reports, and alarm configurations across the platform.
Original Data Remains Unchanged
Unit Conversion never modifies the original telemetry value. The converted result is created as a new Virtual Tag while the source data remains available without any changes.
After the conversion is completed, the generated Virtual Tag can be used like any other telemetry value. It can be added to dashboards, included in reports, and referenced by alarm rules or additional calculations.
