128kbps is equal to 1Mbps per second. This conversion can be understood by multiplying 128 by 8 kilobits per second, which is equivalent to 1024 kilobits per second, or 1Mbps per second. “MB/s” represents Megabytes per second, while “Mbit/s” represents Megabits per second. The former refers to the number of bytes transferred per second, while the latter refers to the number of bits transferred per second. The letter “B” in “MB/s” stands for “Byte,” which represents the quantity of bytes. On the other hand, “bit” represents the quantity of bits. In computers, every eight bits make up one byte, which means 1 byte is equal to 8 bits. Hence, 1MB/s is equal to 8Mbit/s.
