RE: Litre/dm3

[SENES Consultants Limited <senes@senes.on.ca>]

As already noted, the litre (L) is now defined as equal to 1 cubic decimetre (or 1000 cubic centimetres).  However, it was originally defined as the volume of 1 kg of pure water under standard conditions (1 atmosphere and 3.94 degrees C according to an old textbook).  Thus, the old litre was actually about 1000.028 cubic centimetres, or "practically" the same as the new litre.

Isn't science fun?
