Well maybe yes... In the input fields where Gimp expects a number, you can enter expressions. For instance, to scale a 4000px image to half, instead of computing 2000 on the side, you just enter 4000/2 in the size field (and since it already contains 4000, you just add /2).

I never saw an input field on the measurement tool, OP and I are speaking about this tool >

I did tried today, nice and indeed it will be useful.

Two things though, would it be possible to change the PF_INT to something like PF_SPINNER ?
I took the freedom to slightly add 2 code lines to be able to do a Ctrl+Z at once and not have to do it multiple time (I'm no programmer, I hope it's ok)
Here:

Code:

#!/usr/bin/env python

from gimpfu import *
#img = gimp.image_list()[0]

def divide_selection_using_guides(img, x_div, y_div):
    pdb.gimp_image_undo_group_start(img)
    
    if x_div==0 or x_div=="":
        x_div=1
    if y_div==0 or y_div=="":
        y_div=1
        
    pdb.gimp_selection_bounds(img)
    selection_exists = pdb.gimp_selection_bounds(img)[0]
    x1=pdb.gimp_selection_bounds(img)[1]
    y1=pdb.gimp_selection_bounds(img)[2]
    x2=pdb.gimp_selection_bounds(img)[3]
    y2=pdb.gimp_selection_bounds(img)[4]
    selection_width = (x2-x1)*1.0
    selection_height = (y2-y1)*1.0
    
    x_offset = selection_width/x_div
    y_offset = selection_height/y_div
    
    #pdb.gimp_message(selection_width)
    #pdb.gimp_message(x_offset)
    
    
    for i in range(0, x_div+1):
        next_pos = x1 + i*x_offset
        pdb.gimp_image_add_vguide(img, next_pos)
    
    for i in range(0, y_div+1):
        next_pos = y1 + i*y_offset
        pdb.gimp_image_add_hguide(img, next_pos)
    
    pdb.gimp_image_undo_group_end(img)

Again thank you that's a nice script
