• Project Units: Display and calculate depth, length, area or volume using the units from the project coordinate system (see Creating a Project).
• International Metres: Display units in metres. Calculate depth, length, area or volume using the units from the project coordinate system and convert them to metres for display.  
• International Feet: Display units in international feet. Calculate depth, length, area or volume using the units from the project coordinate system and convert them to international feet for display.
