piotrnik, I think you got it wrong. Yes, it's not hard to convert from KB/sec to Kb/sec: Multiply by 8. But that's NOT what we need to do at all! We need to convert from megabits per second to kilobytes per second. Nowhere did I mention converting from KB/sec to Kb/sec! We could certainly "overprovision" the speed that we tell BTSync to use, no matter what the units are for the limits. But if I know my advertised or tested speed in megabits per second, and I am entering an amount in megabits per second, it's just easier. If I'm setting limits, I'm very likely not going to bother setting the limit to what my ISP has promised me. There would be no point in that! I may want to set the limit to half, or one fourth, of what my ISP promises. If I'm setting limits, I very likely know that the advertised speeds are not what I get. I realize that my original suggestion mentioned speeds in terms of what we pay for, and what the ISPs advertise, but actual speed test results from Speedtest.net or similar sites ALSO come in megabits per second, not kilobytes per second. It's just a usability thing. Not like world peace, or hunger in America....
