Found the following definition at http://www.pbdr.com/vbtips/gen/convtwip.htm
Twips are screen-independent units used to ensure that the placement and
proportion of screen elements in your screen application are the same on all
display systems. A twip is a unit of screen measurement equal to 1/20 of a
printer's point. The conversion between twips and
inches/centimeters/millimeters is as follows:
There are approximately 1440 twips to a inch (the length of a screen item
measuring one inch when printed).
As there are 2.54 centimeters to 1 inch, then there are approximately 567
twips to a centimeter (the length of a screen item measuring one centimeter
when printed).
Or in millimeters, as there are 25.4 millimeters to 1 inch, therefore there
are approximately 56.7 twips to a millimeter (the length of a screen item
measuring one millimeter when printed)."""
