Change Dynamo Units

Geometry
1

Hi i was wondering if there is an easy way in Dynamo that changes Revit units from lets say milimeters to meters?
Every time i want to run my script in a new project i first have to change the units in Revit for it to work.

This will automatically set the project units to Meters with no input needed. Wish I could remember which post I got the code from to give kudos. Apologies to the creator.

import clr

clr.AddReference('RevitAPI')
from Autodesk.Revit.DB import *
clr.AddReference('RevitServices')
import RevitServices

from RevitServices.Persistence import DocumentManager
from RevitServices.Transactions import TransactionManager

doc = DocumentManager.Instance.CurrentDBDocument

TransactionManager.Instance.EnsureInTransaction(doc)

unit = doc.GetUnits()
format = FormatOptions(UnitTypeId.Meters)
unit.SetFormatOptions(SpecTypeId.Length, format)

doc.SetUnits(unit)

TransactionManager.Instance.TransactionTaskDone()

OUT = "Project units set to Meters"
