3 ms·Areal is the adjective form of area.by automatic6131 1y agoAreal is the adjective form of area.afandian 1y agoMy question is why add an extra adjective when 'density' is sufficient? Does 'areal density' means 'stuff per area _per area_'? I.e. volmetric?IanCal 1y agoDensity doesn’t mean specifically per unit area though. In fact the default meaning without context to me would be volumetric.
