The following measurement systems are supported in LeaseControl:

• metric;
• U. S.;
• imperial;
• metric with gallons.

The measurement system is set for some macro-objects (units, resources, and users) during their creation. For units and resources, it is the same as in the user settings of the user who creates them; for resources, it is the same as in the settings of the user selected as their creator. You can change the measurement system of existing macro-objects using conversion. Also, users can change their measurement system themselves in the settings.

The measurement system of micro-objects (notifications, geofences, jobs) depends on the resource they belong to. The exceptions are reports, because individual settings are applied to them.

You can also select the measurement system for sensors separately, so that it differs from the measurement system of the unit in the properties of which these sensors are created.

The measurement systems supported in LeaseControl use the following units of measurement:

1 U. S. gallon = 0,833 imperial gallons

1 imperial gallon = 1,201 U. S. gallons

Conversion

Conversion is available only in CMS Manager and can be carried out only by the top user.

The conversion is necessary to change the measurement system for already created macro-objects: units, resources, and users. Without conversion, you can only do this for a user, if you have logged in to the system as this user.

To change the measurement system for a macro-object, follow the steps below.

1. Select Converter in the user menu.
   
   
2. In the drop-down list, select the object type for which you want to carry out the conversion: units, resources, or users. Read more about the conversion particularities of these objects below.
   
   
3. Select the original measurement system which you want to change. After you select it, the objects using this system are listed below.
4. Move the objects for which you want to change the measurement system from the left list to the right. For moving the objects, use the icons  and  or a double click on the row. To select several objects, hold down the Ctrl key and click on the required rows. To select all the objects at once, click Select all.
5. Select the measurement system you want to set for the selected objects.
6. Click ОК to complete the conversion.

As a result, the log shows a record of the completed conversion and the measurement system of the selected objects changes.

Conversion particularities

Below are the conversion particularities of units, resources, and users.

Units

After the conversion, the unit values are recalculated in the following places of the system:

• parameters in the unit properties (trip detection, and so on);
• unit tooltip and extended information;
• event registrar;
• messages;
• tracks.

Resources

After the conversion, the following part of the resource content is recalculated:

• geofence properties (area, perimeter, radius, width);
• job settings;
• notification settings.

The conversion is not applied to report templates. You can set the measurement system for each of them individually in the settings. When a report is executed, the measurement system of the resource in which the report is stored and the measure system of the object on which the report is run are not taken into account.

Users

After the conversion is carried out for a user, the measurement system changes for the Min city radius and Max distance from unit options in the user settings.

In addition, the measurement system set for the user is automatically selected for the units and other users he or she creates (regardless of who is selected as the creator of these objects or in which resource they are created). You can change the measurement system for the user manually at the creation stage.
