panilla [Spanish]

In Spain, a unit of liquid capacity used only for oil, = one hundredth of an arroba of oil or one fourth of a libra of oil. According to the official conversion factors prepared by the royal order of 9 December 1852, an arroba of oil in, for example, Castellón was 12.14 liters, making the panilla 0.124 liters. But the arroba of oil varied from province to province; in particular, in many provinces it was half the size it was in Castellón, sometimes identified as a half arroba and sometimes not. We do not know if there was a correspondingly smaller panilla in such areas.

Others (Doursther, 1840) say the panilla is a unit of capacity the same size as a cuarterón, = one hundredth of an arroba menor, about 0.126 liters.

In the official compilations required by the royal order of 9 December 1852, the panilla is mentioned by name in only one province, Cáceres, at a magnitude of about 0.457 liters.¹
