Ratio measurement scales. The last metric scale is called ratio measurement scales. Ratio along with interval scales affords the most precise data. With both there are equal intervals or units between any two consecutive numbers. The only difference between ratio and interval scales is the role of zero (0).

In ratio scales, zero is real.
