Inputting values
Last update: 09.03.2026
To parse a length string entered by the user, you can use Window.Units.Length.TryParse. As well as converting to system units, this method also handles expressions, and values with explicit units stated:
"(1 + 2) * 3 ^ (3/3 + 3)" = 243
"1cm + 1 1/2 mm" = 0.0115
Window.Units.Angle.TryParse provides the same functionality for angles.
