what is the difference between progress and meter tah?

• The task's progress toward completion is represented by the progress element. The metre element represents a scalar measurement that falls within a predetermined range or a fractional number, such as disc consumption, the usefulness of a search result, or the percentage of voters that chose a particular candidate.

The progress feature displays how far along the task is in reaching completion. A scalar measurement that is within a predetermined range or a fractional number, such as disc consumption, the usefulness of a search result, or the proportion of voters that supported a certain candidate, is represented by the metre element.
