Sorry, you're right. I had meant mW/cc, not W/cc. Until recently Ferroxcube and others had listed their ferrite's hysteresis losses (as a function of frequency and flux density) in terms of mW/cc. Then suddenly their new datasheets changed to KW/m^3. My first reaction was that they must be crazy to apply these enormous units to a ferrite core, a dozen of which would fit in the palm of one's hand! But it quickly became obvious that these units were actually the same as the old mW/cc.
