This is the concept of database units. Database units defined as X/um where X is the database unit scale. X is defined in the technology LEF.

For sky130 the DBU scale is 1000.

In your example, dx = 2500 dbu = 2500/1000 um = 2.5um.

For gf180 the DBU scale is 2000.

In your example, dx = 5120 dbu = 5120/2000 um = 2.56um.
