The Weight of Media

Having recently moved and had to move my audio library I happened to notice it's really heavy. Books are heavy and records are heavy.  Cassettes are light and CDs seem light until you're stacking boxes of hundreds of them. 78s are heavy, but steel-core acetates are heaviest. So I have been thinking about large-scale digitization, and the cloud since I closed the door behind me. The cloud may have it's downside, but it'll never give you a hernia. (I am taking recommendations.)

So to that point I have begun to work out the weights of various audio media.  I have begun with a list of mostly media I already have, and I've added in a few additional sizes and types which I presently do not. rather than calculate these in some very precise minor unit I'm using a postal scale to provide the weights in units that we would all be more familiar with. (Please excuse the awkward columns)

MEDIA TYPE                                             WEIGHT
10.5 inch open reel tape, 1/4 inch and box =   33 ounces
7 inch reel-to-reel tape (1/4 inch) with box =   11 ounces
