A graphical or bar scale. A map would also usually give its scale numerically (“1:50,000”, for instance, means that one cm on the map represents 50,000cm of real space, which is 500 meters) A bar scale with the nominal scale , expressed as both “1cm = 6km” and “1:600 000” (equivalent, because 6km = 600 000cm)
What size is a 1 50000 scale map
Maths (still sorry): A 1:50,000 scale means that each millimetre on your map represents 50,000 millimetres or 50 metres on the ground. (Therefore 2 mm on the map represents 100 metres and 2 cm a kilometre).

How big is a square on a 1 50000 map
How big is a grid square on a 1:50000 map? A grid square on the 1:50,000 scale, is 2cm x 2cm in size, as opposed to the 4cm x 4cm for the 1:25,000 scale. So, although the size on the map is different, the grid squares represent a 1km x 1km square on the actual ground for both scales.
What type of scale is 1 ratio 50000
A 1:50,000 scale map means that 1 cm on the map represents 50,000 cm (i.e. 500 m) in the terrain. “Large-scale” means that the ratio is relatively large, so typically it means there is much detail to see, as on a 1:1000 printed map.
