Spanish to English Other Real Estate

De una lista de parcelas y sus características:

Parcela nº 2: “EL XXXX”

Propietario:

N.I.E.: .
Superficie: 86.193 m2, equivalentes a 8 Has. 61 a. 93 ca.
Coeficiente de propiedad: 4,83

I know that Has. are hectares but I'm not sure of a. or ca. I originally assumed that a. referred to acres but its not possible because 7 hectares is equal to 17 acres.

Thanks in advance for your help!
