On-Screen Takeoff can accommodate both Imperial and Metric Units of Measure (UOM). When a new database is created, choose which measurement to use as default - this can be changed when a Bid is created. All 'UOM' boxes are based on this Bid-level setting.
By default, databases are created in Imperial Measure Mode.

* The roofing industry works with a unit called a Square which equals 10' x 10' or 100 SF. There is no metric equivalent in the roofing industry and a Square is usually considered an Imperial only unit. The metric equivalent of 1 SQ is 9.290304 SQ Meters.
To set an entire database to use Metric measurements, select Metric in the Database Properties (Access) dialog when creating the database. All Bids created in this database will use Metric measurements by default although individual Bids may be set to use Imperial, as needed.
Metric may also be selected on a per-Bid basis.

On-Screen Takeoff relies on specific number formatting to display quantities correctly. If Windows is set to use Regional Settings other than US-English (using commas as thousands separators) metric quantities may not display correctly. Please review this FAQ article: Metric Quantities not Displaying Correctly for instructions on adjusting Windows settings.
When entering a quantity in any Imperial measurement box, the last two digits typed are always interpreted as inches and will always convert to feet. For example: 824 is interpreted as 8 feet, 24 inches and displays 10' 0", 10 is 10" and 1010 is 10' 10".
When entering a quantity in any Metric measurement box, the value is ALWAYS entered as millimeters. Example - to enter 5 meters into a measurement box, type "5000".
