Map scale 1:50,000 means 1 unit on map = 50,000 same units on ground. So 1 mm on map = 50,000 mm = 50 m on ground. 2 cm on map = 1 km on ground. Large scale: 1:5,000 (more detail, smaller area shown). Small scale: 1:250,000 (less detail, large area). SOI topographic maps: 1:50,000 (standard), 1:25,000 (detailed), 1:250,000 (overview).
