Wialon Local works with two measurement systems: metric and U.S. The corresponding parameter could be set for units, resources and users during their creation. Measurement system for routes depends on user's settings at the moment of creation.

The system of measurement for the objects which already exist could be changed with the help of conversion. Only the top level managers have the Converter button in the top panel.

The table below provides you with the units of measurement (and their abbreviations) for both systems:

Metric U.S.
Mileage (large values) Kilometers (km) Miles (mi)
Mileage (small values) Meters (m) Feet (ft)
Speed Kilometers per hour (km/h) Miles per hour (mph)
Fuel amount Liters (lt) Gallons (gal)
Fuel consumption Liters per 100 kilometers (lt/100 km) Miles per gallon (mpg)
Temperature Degrees Celsius (°С) Degrees Fahrenheit (°F)
Area (large values) Square kilometers (km2) Square miles (mi2)
Area (small values) Square meters (m2) Square feet (ft2)

The Converter dialog has the following view:

In the dropdown menu, choose an object type (units, resources, users) over which a conversion will be made. To the right of the dropdown menu there is a brief description of the actions to be made over the objects of a corresponding type.

Below the object type, you choose a conversion pair: from metric into U.S. or from U.S. into metric system, correspondingly. If you choose “Metric ⇒ U.S.”, a list of objects currently using the metric system is formed below. If the conversion pair is “U.S. ⇒ Metric”, then the list of objects currently using the U.S. measurements is formed.

In the list you choose the objects which should be converted. To add these objects for a conversion you should double-click them with the left mouse button or select an object and press 'Add'. The added objects form the list on the right. To remove items from this list double-click them with the left mouse button or select and press 'Remove'. To select multiple items, click on them with the left mouse button holding <Ctrl> button pressed on the keyboard. To implement conversion of the added items press OK. Then confirm your actions in the appeared window. Conversion result can be observed in the log.

Conversion Effects

Ideally, users have the same measurement system as resources and units used by them. In this case everything that the user can see during online tracking in different panels and dialogs and also everything that is received by e-mail using jobs and notifications has the same system of measurement.

For Units

If a conversion is made over units, then units' parameters such as trip detector, fuel consumption settings, counters, etc. will be recalculated. This affects units' representation in the tracking system. Changes will affect not only units' properties, but also displaying of their messages, tracks, tooltips and etc.

:!: Note.
A conversion doesn't influence unit sensors. If it is necessary, their measurement system could be changed manually switching on/off the 'American system' option.

For Resources

If a conversion is implemented over resources, then some contents of these resources, particularly, POIs, circle-shaped geofences, different settings of jobs and notifications, etc. will be recalculated to the other measurement system.

:!: Note.
Measurement system could be set individually in the section of advanced settings for every report template regardless of the resource it belongs to. Units of measurement chosen for one or another report template are given in the resulting report (whether made online or received according to a job or notification). Neither resource measurement system nor measurement system of a unit is taken into account.

For Users

If a conversion is made over users, then the measurement system for the chosen users will be changed. It will affect different online calculations, particularly the work of such tools as Distance, Area, Routing, Nearest units. Address defining parameters will be recalculated as well.

Besides, a measurement system set for the current user is chosen automatically during creating report templates, units, other users, resources (regardless of who is chosen as creator or in which resource an item is created). Herein, on the stage of the items' creation, a measurement system could be changed manually. It doesn't concern such items as POIs, geofences, jobs and notifications, because their measurement system is taken from a resource they belong to.

For Routes

Conversion made over routes touches only their checkpoints — their radius.
