Its most common use is the class of scale or magnitude of any amount. The amount being scaled is 10 and the scale is the exponent. In the logarithmic scale, differences in the order of magnitude can be measured in factors of 10 or decades (meaning the power of 10; not to be confused with the term 10 years). A number is allocated to two sets of quantities. If the quantities are the same, the number has a bigger value. If the quantities are different, the number has a smaller value.
