NetLogo - What is the 1 unit of distance measurement in NetLogo?

Question

I am working on simulating traffic using NetLogo for a postgraduate project.

So that the turtles can move forward, we can indicate the number of units that he can move, for example. fd 1, which would mean that the turtle is moving forward by 1. What is this unit? Is it equal to 1 patch or equal to the size of the turtle?

Answer 1

Each step is the same size as the patches.

Answer 2

, - , , , . fd 0.7 .

Answer 3

Patches represent the carriageway (if you are discussing the simulation of a traffic simulation model), and one layout in size in the corresponding model, for example. 1 patch = 25 m .... etc!
