What is the difference between kilobyte/second and kibibyte/second?

Kilobyte/second (SI) uses decimal prefixes where 1 kB = 1000 bytes, while kibibyte/second (KiB/s) uses binary prefixes where 1 KiB = 1024 bytes.

Why is megabit/second used for internet speed instead of kilobyte/second?

Megabit/second expresses data rates in bits, which is standard in network bandwidth and telecommunications, allowing for consistency in advertising and measuring speeds.

How do I convert kilobyte/second (SI) to megabit/second?

You multiply the number of kilobytes per second by approximately 0.0076293945 to get the equivalent megabit per second value.

What Is This Tool?

This converter tool allows users to translate data transfer rates expressed in kilobyte per second (SI definition) into megabit per second [Mb/s]. It helps compare and report transfer speeds by converting byte-based units into bit-based units commonly used in networking.

How to Use This Tool?

Enter the value in kilobyte per second (SI definition) you want to convert.
Select kilobyte/second (SI def.) as the input unit.
Choose megabit per second [Mb/s] as the output unit.
Click convert to get the equivalent data rate in megabit per second.

Key Features

Converts kilobyte per second (SI prefix, 1000 bytes) to megabit per second.
Uses precise conversion formula based on data transfer definitions.
Supports common data throughput units in IT and telecommunications.
Browser-based and easy to use without installation.

Examples

Convert 100 kB/s (SI) to megabit per second: 100 kB/s equals 0.76293945 Mb/s.
Convert 500 kB/s (SI) to megabit per second: 500 kB/s equals 3.81469725 Mb/s.

Common Use Cases

Reporting simple file download or upload speeds in web or application contexts.
Specifying throughput of embedded devices or serial links transmitting bytes per second.
Measuring internet service plans and network bandwidth in telecommunications.
Describing streaming video bitrates required for smooth playback.
Evaluating storage I/O or backup transfer rates using SI prefixes.

Tips & Best Practices

Ensure you are using the SI-based kilobyte (1000 bytes) rather than binary prefixes for accurate conversion.
Remember that megabit per second expresses data in bits, so factor in that 1 byte equals 8 bits.
Use this converter to align storage or device throughput data with network speed metrics for consistent comparison.

Limitations

Kilobyte per second here uses decimal SI prefixes, differing from binary units like kibibyte per second (KiB/s = 1024 bytes), which can lead to confusion if mixed.
Megabit per second is in bits, so interpretation requires conversion between bytes and bits.
Discrepancies may arise if different unit definitions are not carefully considered in conversions.

Frequently Asked Questions

What is the difference between kilobyte/second and kibibyte/second?: Kilobyte/second (SI) uses decimal prefixes where 1 kB = 1000 bytes, while kibibyte/second (KiB/s) uses binary prefixes where 1 KiB = 1024 bytes.
Why is megabit/second used for internet speed instead of kilobyte/second?: Megabit/second expresses data rates in bits, which is standard in network bandwidth and telecommunications, allowing for consistency in advertising and measuring speeds.
