Questions tagged [units]

Prior to version 2.9 Blender's default distance unit was an arbitrary Blender distance, known as None. Starting in version 2.9 Blender's default distance system is metric and the default distance unit is the meter. There are also units for mass, time, temperature and rotation. Units can be used when specifying transforms and can be relevant when importing and exporting. Use this tag for questions related to units and their uses.
