Hard to compare table's data size

[pixcc]

I was comparing the size of the data in the two tables to see which of the two tables was larger. I found the information I needed in the Info tab of the table, under the Table Stats section. One table had 132 MB and this was very clearly displayed, the other table displayed 78 213 KB, which equates to about 78 MB. I needed to do a calculation in my head to compare the sizes, couldn't do it with a quick glance.
