The Home Depot [ http://www.homedepot.com ], [ http://www.homedepot.ca ] has a number of calculators available to determine how much supplies are need for a project of a given size. They provided a metric input option, however there were a number of glaring errors: 1) they had two blanks for input, one for metres (abbreviated as 'M') and one for centimetres (correctly symbolized as 'cm') much as one would have for feet and inches. However it does accept decimal fractions of a metre and cm over 100. They did not give the mm option which I found surprising since most construction in North America uses the mm as the basic unit of measure. 2) the materials listed were only given using the WOMBAT dimensions and not soft metric 3) the output was always in American gallons, inches, feet, yards, etc. rather than litres and metres. They have a user-friendly contact form an I urge you to write them to ask them to make a few subtle improvements. greg
