First of all I assume you are in reprap mode as the UM2 and UM3 support a weird mode called ultigcode but can also do reprap mode. Every other printer in the world does normal gcodes basically.
The extrusion is in mm length of filament. So it matters the diameter of the filament.
For example lets say you print a "line" of filament 100mm long. Let's say the nozzle is .4mm wide and the layer height is .1mm. The volume of filament is 100*.1*.4 or 4 cubic mm.
If you have 1.75mm diameter filament the area of that filament is PI * (1.75/2) ^2 or 2.4 mm^2 area. 4 / 2.4 gives you 1.666mm of travel for E axis.
So if E had been at position zero and x,y was at 0,0 then you could do something like
G0 X100 Y0 E1.666
You can also reset the extruder (or any axis) with G92 command so for example even if extruder is 2 meters into a print job you can do:
G92 E0
G0 E1.666
and it would extrude the amount of filament for a 100mm long line at .1mm layer height and .4mm nozzle width.
That's how Cura does it.

Cura 5.7 is here and it brings a handy new workflow improvement when using Thingiverse and Cura together, as well as additional capabilities for Method series printers, and a powerful way of sharing print settings using new printer-agnostic project files! Read on to find out about all of these improvements and more.
S-Line Firmware 8.3.0 was released Nov. 20th on the "Latest" firmware branch.
(Sorry, was out of office when this released)
This update is for...
All UltiMaker S series
New features
Temperature status. During print preparation, the temperatures of the print cores and build plate will be shown on the display. This gives a better indication of the progress and remaining wait time. Save log files in paused state. It is now possible to save the printer's log files to USB if the currently active print job is paused. Previously, the Dump logs to USB option was only enabled if the printer was in idle state. Confirm print removal via Digital Factory. If the printer is connected to the Digital Factory, it is now possible to confirm the removal of a previous print job via the Digital Factory interface. This is useful in situations where the build plate is clear, but the operator forgot to select Confirm removal on the printer’s display. Visit this page for more information about this feature.
