Hi there Salman,
The measurements are stored in centimeters, as the rangings from the device are returned with centimeter resolution. Currently, there is no way to change the units used in the Visualizer.
If you are looking to work with data in different units, you could always convert existing data. For example, the default output
.csv file will look something like this:
See here for additional information.
You could open this file in any program and easily convert the 3rd column (distance) from
cm to any other unit you like.
