EC meter µS and PPM

[hird]

Hi,
I have bought and tested my EC meter (HM Digital COM-80 EC/TDS HydroTester).
When I test my tap water it says something like 130µS, but the run off from my soil can be up to 800.
So I wonder what is normal readings and what should I aim for. I do understand that no one can tell me exact since every plant is different and abosorb nutrients at different pace.
So does anyone else use EC meters and measure in µS?
What does your readings say?

The youtube videos I have been looking at always talks about PPM, but after some reading im under the impression that EC with µS measurements would be more accurat.

Does µS equal ppm/2 ?

The spesification info

Hi there
I hope so, I will test the meter abit more now. Read that since my meter show both I can just switch between and see the ratio. But I still don't understand why people use ppm when EC is more accurate. Why not just use µs measurements.

And nope, still don't understand it. No result gets Divided by the same amount. I'll just use the ppm part of my EC meter hehe.
