Internet Download Calculator

This narrowly focused app calculates total download time but offers no other features. Internet Download Calculator doesn't require installation; just unzip and run the executable file and input file size and Internet speed, and results are rapidly returned down to the second. Note, however, you must first convert MB to KB and Internet speed to equivalent transfer rate (KB/s) using the provided buttons. Internet Download Calculator doesn't include a Help file, though one isn't really necessary. Those with slower connections might find some benefit in the information Internet Download Calculator provides, but most users won't be overly impressed with this single-purpose application. That said, this freeware does exactly what it says and anyone can use it.
