What is the difference between megabyte/second and megabyte/second (SI def.)?

Megabyte/second may be based on binary or decimal definitions, while the SI definition strictly uses decimal units with 1,000,000 bytes per second.

Why is conversion between these units necessary?

Converting ensures consistency when reporting data transfer rates across different devices and standards, especially in engineering and benchmarking contexts.

Can all devices' speeds be directly compared without conversion?

No. Because some devices use binary-based definitions and others use decimal SI units, direct comparison without conversion can be misleading.

What Is This Tool?

This tool helps convert data transfer rates from megabyte per second (MB/s) using the binary-based interpretation to the decimal SI-based megabyte per second standard. It standardizes data throughput values for clearer comparison and engineering accuracy.

How to Use This Tool?

Enter the data transfer rate value in megabyte/second [MB/s].
Select the target unit as megabyte/second (SI def.).
Click convert to obtain the corresponding rate in decimal SI units.
Use the converted value for consistent reporting or technical documentation.

Key Features

Converts between binary-based and decimal-based megabyte per second units.
Useful for storage device throughput and network transfer rate standardization.
Includes precise conversion factors reflecting the definition differences.
Browser-based and easy to use without installation.

Examples

Convert 5 MB/s to SI definition: 5 × 1.048576 = 5.24288 MB/s (SI def.)
Convert 10 MB/s to SI definition: 10 × 1.048576 = 10.48576 MB/s (SI def.)

Common Use Cases

Reporting sequential read/write speeds of HDDs and SSDs.
Measuring file transfer speeds over USB or Ethernet using decimal units.
Describing large file download/upload rates for network-attached storage.
Ensuring standardized throughput values in cloud computing and multimedia streaming.

Tips & Best Practices

Verify which megabyte definition (binary or decimal) is used by your device or software.
Use this conversion to align reported speeds with SI decimal units for clarity.
Apply consistent units across documentation to avoid confusion.
Note the binary vs decimal distinction when comparing transfer rates from different sources.

Limitations

Differences between binary and decimal definitions of megabyte can cause misinterpretation.
Some devices/software may apply units inconsistently, affecting comparability.
Conversions depend on precise knowledge of the unit conventions used.

Frequently Asked Questions

Key Terminology

Megabyte/second [MB/s]: A data transfer rate equal to one megabyte of data moved each second, where megabyte can be based on decimal or binary definitions.
Megabyte/second (SI def.): A standardized data transfer rate representing exactly 1,000,000 bytes per second, based on decimal SI units.
Data transfer rate: The speed at which data is moved from one place to another, usually measured in bytes or bits per second.
