Old Croatian land units
Older Croatian land registry and cadastre records, inheritance documents and rural property listings sometimes still use the units of the former Austro-Hungarian cadastre:
- Square fathom (četvorni hvat, čhv): 3.596652 m². A plot of 500 čhv is about 1,798 m².
- Cadastral yoke (katastarsko jutro): 1,600 čhv = 5,754.64 m², a little over half a hectare.
Current land registry extracts state areas in m². If a listing gives the plot size in čhv or jutro, convert it before comparing prices per m².
Horsepower
European car documents use kW. Metric horsepower (PS) is 0.7355 kW, while UK/US horsepower (hp) is 0.7457 kW, so 100 kW ≈ 136 PS ≈ 134 hp.
