why resistors are manufactured with standara values?

[the moon is back]

hi, can anybody tel me why resistors are manufactured only with standard values?
thank u

Also, why are sugar cubes not manufactured in 3cmx1cmx1cm sizes, for those that want more sugar in their coffee? Do you know?

Because nobody wants a 4.21567Kohm resistor, not enough
to be worth all the special handling. Mass production to a
target, or a manageable number them, is where it's at.

Absurd we have a particular resistor for every purpose and to suit that we can't use an arbitrary resistance but we go specific resistance how to go for specific ones with out any specifications

The resistor values for each series are calculated based on the tolerance they have so that they don't overlap, they are not random

The use of reduced range series implies in a reduced BOM itens variety, reducing supply cost.
Other advantage - regarding SMD assembly - is reduction of reel exchange performing work with less steps.
