Please check:
- linear factor of dimension created (options tool bar when drawing dimension, should be 1:1)
- Edit > Drawing Preferences > Dimension > Dimension Settings > Linear Dimensions > Format / Precision

If problem persists, please re-open and provide additional information (dimension tool used, screenshots, etc.)

Please check pdf attached. Horizontal dimension tool send a value of 66 while the info fuction sends the right value of 5.5 inches if you try it on the attached drawing. PDF shows all drawing dimensions preferences

The problem would likely be the factor in the marked field (echelle), see attachment.

For existing dimensions, you can change the linear factor using the property editor (see attachment).
