Use system units

Tedds for Word contains a number of pre-defined system units that you can use in all of your calculations. The following paragraphs teach you how to use, view, add, and remove system units.

Note:

The following only applies to Tedds for Word.

Use system units in calculations

Do one of the following:

Type the unit after a value or a results field.
In the Insert ribbon group, click Units, and in either the SI Units or US Units list, select the desired unit.

The selected unit appears in your document.

View all system units

In a Tedds for Word document, type ListAllUnits() = ?
Calculate the document.

Tedds for Word lists all available system units in your document.

Add system units

Note:

If you have the right to access the units database file, the new unit will be permanently added into system units.
If you do not have the right to access the units database file, the new unit will only be available in the current calculation process.

In a Tedds for Word document, type AddUnit($x$, #a#, #b#, #c#, #d#, #f#) = ?
where
- $x$ is the name of the unit which you want to add
- #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.
Calculate the document.

Tedds for Word adds the unit to the unit database.

Delete system units

Warning:

Before you delete a system unit, note that:

The unit will no longer be available for you to use.
Any calculations that use the deleted unit will no longer calculate correctly.
If you have the right to access the units database file, the unit will be permanently deleted from system units.
If you do not have the right to access the units database file, the deleted unit will no longer be available in the current calculation process.

In your document, type RemoveUnit($x$)
where
- $x$ is the name of the unit which you want to remove
Calculate the document.

Tedds for Word deletes the unit from the unit database.
