When using python bpy I can change the default "view" units to cm:

bpy.context.scene.unit_settings.length_unit = 'CENTIMETERS'

However, all the input is still in meters. For example if I change the camera location to:

cam.location = [0, 0, 5]

Blender thinks it's 5 meters ie 500 centimeters and not 5 centimeters.

How can I change the "bpy" settings to understand I'm using centimeters?

Use unit_settings.scale_length link to convert between blender units and dimensions.

import bpy
bpy.context.scene.unit_settings.scale_length = 0.01
bpy.context.scene.unit_settings.length_unit = 'CENTIMETERS' 
cam = bpy.context.object
cam.location = [0, 0, 5]
