Time in the dungeon is measured in game turns, which are (approximately) 10 minutes long. When combat begins, the time scale changes to combat rounds, which are (approximately) 10 seconds long. Thus, there are 60 combat rounds per game turn.
Distances in the dungeon are measured in feet. Outdoors, change all distance measurements (movement, range, etc.) to yards (so 100’ becomes 100 yards) but area of effect measurements (for spells, for instance) normally remain in feet.
