Yes it's more complicated. First of all it's in mm/minute so just divide by 60 to get mm/sec.
example: 100mm/sec is feedrate of 6000.
Feedrate is the requested speed for ALL 4 AXES. It's an old term for old CNC and other machines e.g. milling machines and lathes. It is used because certain materials can be cut at certain feed rates.
Anyway - back to 3d printing. It is the requested speed for all 4 axes (X,Y,Z,E) so if you then do a movement in only one axis that axis will go at that speed but is constrained by the max speed for that axis. Also movement is constrained by max jerk setting and by acceleration for that axis. If you make a movement using multiple axes (most often you move X,Y and E at the same time) Marlin will move linearly. It won't move all axes at max speed because then you wouldn't get a straight smooth movement. You want the E axis to speed up at the same time as you speed up the other 2 axes and so on. So the actual movement speed may be slower but Feedrate is the desired speed.
On the control panel for UMO and UM2 you can go into TUNE menu and adjust the requested speed by a certain percentage. Marlin will multiply this by the gcode feedrate to get a REQUESTED speed. The actual speed may be lower, again due to acceleration or max speed on any of the axes that are moving.
It's rare for the Z axis or the E axis max speed to restrict the actual speed. Usually the X and Y axis are the axes going as fast as possible (at the requested feedrage). So most people think of this as the X and Y speed but in reality the "F" parameter controls all 4 axes.

Strap in for the first Cura release of 2024! This 5.7 beta release brings new material profiles as well as cloud printing for Method series printers, and introduces a powerful new way of sharing print settings using printer-agnostic project files! Also, if you want to download the cute dinosaur card holder featured below, it was specially designed for this release and can be found on Thingiverse!
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.
