Measuring on an interval scale provides information about the size of the differences between the measurements, which is not possible with an ordinal scale. While ordinal scales rank order the items being measured, they do not provide any information on the magnitude of the differences between the items. Interval scales, on the other hand, have equal intervals between values, allowing for more accurate comparison of measurements.
