In a logarithmic scale, numbers are arranged in such a way that any pair of numbers that are related to each other in such a way that one is half the size of the other will always be the same distance from each other on the scale. The figure below shows a horizontal logarithmic scale. | ||

For example the distance between 4 and 8, 20 and 40, or 100 and 200 is the same in all three cases. | ||
