An input unit can be converted to any number of output units—the outputs are specified as a "combination" by separating unit codes with a space (" ") or a plus (" + "). Using a space as a separator does not work if any of the unit codes contains a space. For example, each of the following converts 1.2 km 2 to acres, square yards, and hectares.
T scale, using 3 mm gauge track to represent standard gauge railways. 1:450. 0.677 mm. Model railways (T) T scale, using 3 mm gauge track to represent 3 ft 6 in ( 1,067 mm) gauge railways. Hasegawa also produces plastic ship models in this scale. 1:432.
