Select the items that need to have the texture scaled, then select Properties: Texture Mapping: Apply Box Mapping

Select BoundingBox and click on screen to set the first corner (it's not too important where, it could be a corner).

Use the length of the texture (Bricks_1m) in this case 1m or 1000mm

Press Enter to use the width for the height, creating a 1000mm cube.

Capping is the top surface of the object.

The texture is now scaled to 1m or 1000mm along the X, Y and Z axis.
