'''Acetabulum''' was a [[Ancient Rome|Roman]] measure of capacity, both fluid and dry, equivalent to the [[Greek Language|Greek]] ὀξύβαφον (oxubaphon) and equal to about 66.375 milliliters in volume. It was one fourth of the ''hemina'' (equal to about 265.5 milliliters), and one eighth of the ''sextarius'' (which was about 567 milliliters).

The acetabulum is the concave articular surface of the pelvis, formed by the parts of three bones, the ilium, ischium, and pubis. The head of the femur articulates with the pelvis at the acetabulum, forming the hip joint. In reptiles and in birds, the acetabulum are deep sockets. It has its counterpart in the pectoral girdle, namely, glenoid fossa.

The word acetabulum originally meant 'little vinegar cup,' and was the Latin word for a small vessel for storing vinegar. The word was later also used as a unit of volume, equal to roughly 270ml.
