and Edit User-Created Conversions:
All user-created units and conversion data can be edited using this Review/Edit
User Conversions window. Only
user-created units may be edited. All
measurement units included with Unit Converter have been checked for accuracy
and are protected from alteration. Please
contact the author if you find problems with any of the included measurement
units and I’ll fix them for you.
Once you’ve selected the measurement unit to review and/or edit,
you’ll find two main sections in this window for reviewing and modifying data
associated with that unit. The
first section, labeled “Secondary Conversion:”, contains the data
describing the actual measurement unit you’ve selected, including the input
and output conversion factors to convert that unit to it’s associated Primary
conversion unit and the name of that Primary conversion unit.
If the measurement unit you’ve selected happens to be one of the
Primary conversion units, then label over the Primary Conversion Unit box will
The second section, labeled “Primary Conversions for measurement class units”, lists the conversion factors between the Primary measurement units in that measurement class. This section can only be edited if your selected unit is one of the Primary measurement units.
The Review/Edit User Conversions worksheet is shown below. Click on any part of it to see an explanation of that function:
Unit: Here is where you
select your user-created measurement unit.
This box will list only those measurement units that have been
created by the user.
Class: Once you have
selected your measurement unit, the measurement class of that unit will
appear in this box. This value
cannot be edited.
Conversion Unit for Selected Unit:
All measurement units have a Primary measurement unit to convert to,
and this box displays the primary unit associated with your selected unit.
You can change the primary unit by clicking on the box and selecting
a different one. If your
selected unit IS the primary unit, then the label for this box will turn
green to alert you to that fact. In
this case, you probably will want to leave all the “Secondary
Conversion” data alone since this secondary conversion only converts the
unit to itself. However, having
a primary unit as your selected unit allows you to change the “Primary
Conversions” data. You can
only modify the “Primary Conversions” data if you have selected a
Primary unit in the “User-Defined Units:” box.
Unit Input Name – Singular: This
is the singular form of the name of your selected measurement unit (i.e. Foot
instead of Feet). Unit
Converter uses the singular form of the name in the one-to-one conversions.
Unit Input Multiplicative Conversion Factor:
This is the multiplicative conversion factor for converting your unit
to the Primary measurement unit.
Unit Input Additive Conversion Factor:
This is the additive conversion factor for converting your unit to
the Primary measurement unit.
Unit Output Multiplicative Conversion Factor:
This is the multiplicative conversion factor for converting the
Primary measurement unit to your unit.
Unit Output Additive Conversion Factor:
This is the additive conversion factor for converting the Primary
measurement unit to your unit.
Unit Definition: This
is the definition entered for the selected measurement unit.
Conversion Data: These
are the conversion factors for converting between the primary units of the
measurement class. You can only
edit these data if you have selected one of the primary conversion units as
your selected unit, and if you created these conversion factors originally
using the Primary Unit Worksheet. None
of the original conversion factors that come with Unit Converter can be
edited. To edit these data,
just type new values in the table. The
field sizes can be changed by positioning the cursor between the field
headers and dragging on them.
