How much kbps download speed can get in 1MB cir connection?

A 1 MBps (megabyte per second) CIR (Committed Information Rate) connection translates to a download speed of approximately 8,000 kbps (kilobits per second), since 1 byte equals 8 bits. Therefore, if you have a 1 MBps connection, you can expect to achieve around 8,000 kbps under optimal conditions. However, actual speeds may vary based on network conditions and other factors.
