Download Calculator for Mac

From Gavin Shapiro:

With this program, you can enter the amount of memory a file takes up (in kilobytes or megabytes), and then a speed for how fast the download is going. You can enter this in kilobytes per second or megabytes per second. Unlike other programs, you do not have to use set speeds (ie, 56k modem, T1 line). Then you can see how long it will take to download that file, assuming that you get that speed at a constant rate. This program is great for estimating how long a download will take on any kind of connection speed, and it is easy to use. The reason I wrote it was because calculating everything with a calculator was a hassle.
