### Dicom Unit Symbol Convention

When you use units in calculation or conversion you can express that in Dicom Calculator and Dicom Document in one of the the followoing three manners:

1. Unit symbols without any braces - these are the unit symbols standarised by International System of Unit (SI).

Example:

m. - metre

ft. - feet

mi. - miles

2. Unit symbols with curly braces {} - these are not standard symbols but widely used.

Example:

{inch.} - inches

{km.} -kilometres

{cm.} - centimetres

3. Unit symbols with square braces [] - these are non-standard symbols and also not widely used.

Example:

[fath.] - fathom

[micron.] - micro metre

In all of the cases above use of period (.) next to the unit symbol is optional. Also the use of {} or [] are optional.When the option "File > Preferences... > Calculation and Editing > Check keywords" is checked on (by default it is on) any unit symbol written is automatically reformatted in Dicom Calculator and Dicom Document.

That means you can write {inch.} in any of the following manner:

inch

inch

{inch}

{inch.}

and even [inch] or [inch.]

Dicom will reformat to its standard convention - {inch.}
