Total known weight

Total known weight (TKW), also total known mass,[1][2] is a term used mainly by dealers and meteorite collectors to indicate the combined weight of all known pieces from a single named meteorite. The total known mass of a named meteorite is a fraction of the mass of the original meteoroid that entered Earth's atmosphere to produce the meteorite (also called post-atmospheric mass).
