Beschreibung
Einheitenrechner Der Einheitenrechnerdialog ermöglicht es, Mengen in verschiedenen Einheiten zu berechnen.
The Units calculator dialog box
Usage
- Select the Tools →
Units calculator... option from the menu.
- The Units calculator dialog box opens. For more information see Options.
- The dialog box is modeless, meaning it can stay open while you continue working in FreeCAD.
- Press the Close button to close the dialog box.
Options
Top row
- Enter a value with units in the first input box. For example
10 mm
.- Units with exponents should be entered using the
^
notation. For example1 m^2
. - If the input value cannot be recognized or if the units are unknown the => box will display the 'syntax error' message.
- Units with exponents should be entered using the
- Enter the target units in the as input box. For example
in
.- If the units are unknown the => box will display the 'unknown unit' message.
- If the units in the first and second input box do not match, the => box will display the 'unit mismatch' message. In the example the units match as 'mm' and 'in' are both length units.
- If there are no input errors the => box will immediately show the result. For the example values the result is
0,394 in
. - Optionally press the Copy button to copy the content of the => box to the clipboard. The value can then for example be pasted in a FreeCAD task panel or dialog box.
Text area
- The conversion performed in the top row can be copied to the text area by pressing Enter in the first or second input box.
- The text area can contain multiple conversions and its content can be selected and copied to the clipboard with Ctrl+C and used in other programs.
Quantity
This new part (introduced in version 0.19) of the Units calculator still suffers from some bugs.
- Select an option from the Unit system dropdown list. This will be the target unit system. Select Preference system to use the unit system defined in the Preferences.
- Select an option from the Unit category dropdown list.
- Enter a value with units in the Quantity input box. The units must match the unit category.
- If the Area unit category has been selected, entering certain units is problematic. For example to enter
m^2
you have to first enter^2
, put the cursor before the^
character and then enterm
.
- If the Area unit category has been selected, entering certain units is problematic. For example to enter
- Click in the Decimals input box and press Enter to convert the value in the Quantity input box.
