斤两 literally combines the Chinese weight units 斤 (catty, ∼500g) and 两 (tael, 1/16 catty). As a noun, it refers to literal weight measured in these units, but is more commonly used figuratively to mean the 'weight' or substance of a person's words, actions, or status — similar to 'heft' or 'significance' in English. You'll hear it in phrases like 有斤两 ('has weight/pull') or 没斤两 ('lacks substance').
