Decimals/Fractions: Click this drop-down list to select the number of decimals or the size of fractions for the chosen Length Measurement Unit.
Note: If you change the Working Units (for example from metric to imperial), some of the other default values such as grid spacing or default element sizes may need adjusting for meaningful, round values.
Note: The Length Unit entered here does not apply to Dimensioning functions. To set Dimension units, use Options >Project Preferences > Dimensions.

This setting also affects the Leading value in Texts and Dimension Texts.
