ವಿಕಿಪೀಡಿಯ:WikiProject Geographical coordinates/dim:

The dim: parameter specifies the width of the object in metres or kilometres, overriding the scale implied by any type: parameter.

Syntax — dim:<width><units>

width — integer number of metres (m) or kilometres (km)

units — m or km, if not specified, defaults to m

GeoHack uses dim: to select a map scale. If no dim:, type:, or scale: parameters are provided, GeoHack uses its default scale of 1:300,000.
