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.

Units are a Scene Property in Blender. The default units for a scene can be found in the Properties Editor in the Scene Properties tab in the Units panel:

Why do we apply location, say after we moved an object

Why do we apply that location. If I have multiple objects in blender, I can relatively see each coordinates, and add new one based on existing. If I reset all will be zeros, so nothing to compare.

2 = 1 Why are values I enter in Blender getting halved?

After I enter a value of '1', it gets divided by '2'. Why does this happen, and how do I get rid of it? This happens everywhere where I enter a value. Enter '4' it becomes '2', enter '16', it becomes '8'. Are one of my settings wrong or something?
