What is the difference between megabyte per second (SI) and megabit per second?

Megabyte per second (SI) measures data transfer in bytes, with 1 MB/s equal to 1,000,000 bytes per second. Megabit per second measures transfer in bits, with 1 Mb/s equal to 1,000,000 bits per second.

Why is it important to convert between MB/s and Mb/s?

Converting between these units allows clear comparison between storage device speeds and network bandwidth, which use different units to express data transfer rates.

Does this converter use binary or decimal definitions?

The converter uses decimal (SI) units for megabyte per second and bits per second for megabit per second, not binary definitions.

Common Use Cases

Reporting sequential read/write speeds for storage devices like SSDs and HDDs
Specifying file transfer speeds over USB, Ethernet, and similar interfaces using decimal SI units
Advertising consumer internet plans in terms of network bandwidth
Measuring video streaming bitrates in telecommunications
Comparing data throughput rates between storage systems and network connections

Tips & Best Practices

Ensure consistent use of units when comparing or converting data rates
Remember that 1 byte is equal to 8 bits when converting between byte-based and bit-based units
Be aware of the difference between SI and binary-based definitions to avoid confusion
Use examples to verify typical conversions before applying values in technical specifications

Limitations

Megabyte/second uses bytes, while megabit/second uses bits, so conversion depends on the 8 bits per byte ratio
The SI megabyte differs from binary units like the mebibyte, which can affect conversions
Rounding in conversion factors may lead to small discrepancies in very precise calculations
