I would appreciate if somebody can explain me the following line in the library code of enviroplus, I would like to know what 56000 means, it is 56000 kohm or 56000 ohm?

ox = (ox * 56000) / (3.3 - ox)
except ZeroDivisionError:
ox = 0

Thank you so much

The datasheets are vague to me, but the main sheet does note that “Depending on the application and on the precision of the A/D converter, a single load resistor of 56 kOhms may be sufficient”.

Exactly what that formula is doing though I don’t know.
