Hi Matt -
Not yet, however this feature has been a requested before and we do see the value it can bring.
To aid you currently, you can reference the height of the origin's green axis in Visualize Preview mode. This height is exactly 1 meter. You can also click Tool > Options > 3D Viewport and scroll down to the bottom to show model bounding box. This will show each models bounding box, with a dimension on each side, also in meters.
Also, turning on Model Bounding Boxes and/or Part Bounding Boxes can aid as well. With these on, while in Preview Mode (ONLY) you will see green bounding boxes around models and/or parts, with text along each edge indicating the size of the box, in METERS.
