What Is This Tool?
This tool converts data transfer speeds between gigabyte per second (using SI definitions) and megabyte per second, helping users accurately compare and analyze throughput rates across different devices and networking environments.
How to Use This Tool?
-
Enter the value in gigabyte per second (SI definition) you wish to convert
-
Select gigabyte/second (SI def.) as the source unit
-
Choose megabyte/second [MB/s] as the target unit
-
Click the convert button to see the result expressed in megabytes per second
Key Features
-
Converts data transfer units using standard decimal SI definitions
-
Supports conversion for network and storage device throughput rates
-
Provides clear and precise unit transformation from gigabyte/second to megabyte/second
-
Browser-based and easy to use without requiring installation
Examples
-
1 gigabyte/second equals approximately 953.67 megabyte/second
-
0.5 gigabyte/second equals roughly 476.84 megabyte/second
Common Use Cases
-
Specifying data center or network link throughput for backbone or aggregation interfaces
-
Describing sequential read/write speeds for SSDs and NVMe storage arrays
-
Measuring file copy or backup transfer rates in local network environments
-
Monitoring cloud and network storage upload or download performance
-
Expressing interconnect or memory bandwidth in high-performance computing systems
Tips & Best Practices
-
Always confirm the unit definition (SI decimal vs binary) to ensure accurate conversions
-
Use this conversion to compare hardware and network performances precisely
-
Consider possible overheads and protocol impacts not reflected in pure unit conversions
-
Apply this tool when needing granular measurements in megabyte scale from larger gigabyte units
Limitations
-
This conversion applies only to decimal SI unit definitions, excluding binary prefixes like MiB
-
Differences between decimal and binary unit definitions can cause discrepancies
-
Real-world throughput may differ due to network latency, protocol overhead, and hardware limits
-
The tool performs a mathematical conversion and does not measure actual transfer speeds
Frequently Asked Questions
-
What does gigabyte/second (SI def.) mean?
-
It is a measurement of data transfer speed where one gigabyte equals 10^9 bytes transferred every second, following decimal SI prefixes.
-
How is megabyte/second [MB/s] defined?
-
Megabyte per second represents the rate of transferring one megabyte of data per second, with megabyte possibly using decimal or binary bytes definitions.
-
Why might conversions between these units differ?
-
Conversions differ because gigabyte/second and megabyte/second units here use decimal definitions, while some systems use binary prefixes, which affects the value scale.
Key Terminology
-
Gigabyte/second (SI def.)
-
A data rate unit representing one gigabyte (10^9 bytes) transferred per second using the decimal SI definition.
-
Megabyte/second [MB/s]
-
A unit measuring data transfer speed as one megabyte moved every second, using decimal or binary byte definitions depending on context.
-
SI Prefix
-
Standard decimal prefixes used internationally to denote multiples of units, such as kilo (10^3), mega (10^6), and giga (10^9).
