This figure is over 3 years old; hardness may have changed.
The only figure we could verify for Miskolc is a February 2017 average of chemical tests, 167.8 mg/L CaO or 16.8 °dH as printed, which we convert to about 300 mg/L CaCO₃. It is stale, and the PDF does not name its publisher. Treat the number as indicative only.
Hungarian suppliers report total hardness in German degrees (nk°) or mg/L CaO; the limit is 50–350 mg/L CaO.

What it means at home
- Severe scale: heater elements and washing-machine heaters fail early.
- Detergent use is very high; taps and screens coat within days.
- Dishwasher at maximum salt setting.
- An ion-exchange softener is practically essential; RO for drinking water.
How much salt will you use for softening?
Yes. At this hardness a softener pays for itself through appliance life and detergent.
Descale a coffee machine or kettle about every 1 months (typical manufacturer guidance for this hardness).
