- #a# is the power of the unit dimension M^a
- #b# is the power of the unit dimension L^b
- #c# is the power of the unit dimension T^c
- #d# is the power of the unit dimension θ^d
- #f# is the multiplication factor that you need to apply to the Tedds base units to change the base units to the unit symbols (such as h for hour) of the unit that you are adding.
