 steps:

 1. in Browser, open a basic web layout
 2. view map in 1:100000 scale so that we can verify the calculation easily
 later
 3. click 'Measure' button, so there is a Measure Distance dialog in Task
 pane
 4. select Measure units as Kilometers
 5. Draw a 1 cm long line on the map, so in Measure dialog, it displays
 Segment: 1.00 (Kilometers), Total: 1.00 (Kilometers)
 6. select Measure units as Meters
 7. you will find : the segment: 1.00(Meters), Total: 1.00 (Meters)
 8. continue to draw another 2 cm long line on the map

 result: the segment: 2000.00(Meters), Total: 2001.00 (Meters)

 expected: the segment: 2000.00(Meters), Total: 3000.00 (Meters)

 regression:
 no, it exists in Knight. but  Jedi,  it does't have such use case (as user
 can't change the unit).
