Opens the unit calculator dialog, which allow to transform Quantities into different units.

==Description== <!--T:3-->
  
The first field defines a a value and a corresponding unit (what kind of units get recognized you can see in the [[Quantity]] description). In the second field you specify the resulting unit. The third field present the result. Pressing return in field one or two will add the result of the calculation to the log area for later usage.

The '''Std UnitsCalculator''' command opens the Units calculator dialog box. The Units calculator can be used to convert values from one unit system to another.
  
If one of the fields get red in the background means an error occourd. Either the parser gets and error in the unit expression or the source and target unit do not fit. Hovering over an red input field shows you the error string.

Description

The Std UnitsCalculator command opens the Units calculator dialog box. The Units calculator can be used to convert values from one unit system to another.

The Units calculator dialog box


Usage

  1. Select the Tools → Std UnitsCalculator.svg Units calculator... option from the menu.
  2. The Units calculator dialog box opens. For more information see Options.
  3. The dialog box is modeless, meaning it can stay open while you continue working in FreeCAD.
  4. Press the Close button to close the dialog box.

Options

Top row

  1. Enter a value with units in the first input box. For example 10 mm.
    • Units with exponents should be entered using the ^ notation. For example 1 m^2.
    • If the input value cannot be recognized or if the units are unknown the => box will display the 'syntax error' message.
  2. 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.
  3. If there are no input errors the => box will immediately show the result. For the example values the result is 0,394 in.
  4. 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

  1. The conversion performed in the top row can be copied to the text area by pressing Enter in the first or second input box.
  2. 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.

  1. 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.
  2. Select an option from the Unit category dropdown list.
  3. 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 enter m.
  4. Click in the Decimals input box and press Enter to convert the value in the Quantity input box.

Notes

  • See the Expressions page for a list of all known units.
