What Is This Tool?
This tool converts data transfer rates from kilobyte per second (SI definition), which uses decimal measurement units of 1000 bytes per second, into modem (110) speeds, representing old legacy modem rates at approximately 110 bits per second. It helps users compare modern byte-based rates with historical bit-based standards.
How to Use This Tool?
-
Enter the value in kilobyte per second (SI def.) you want to convert
-
Select the target unit as modem (110) to perform the conversion
-
Click the convert button to get the equivalent modem (110) rate
-
Review the result for your application or comparison needs
Key Features
-
Converts data transfer rates between kilobyte/second (SI def.) and modem (110)
-
Uses a fixed conversion rate linking bytes per second to bits per second legacy speeds
-
Supports use cases in vintage computing, telecommunications history, and protocol testing
-
Provides clear numeric examples for easy understanding
-
Browser-based and straightforward to use
Examples
-
1 kilobyte/second (SI def.) equals approximately 72.73 modem (110)
-
5 kilobyte/second (SI def.) equals approximately 363.64 modem (110)
Common Use Cases
-
Reporting simple file download or upload speeds in web and application environments
-
Specifying throughput for embedded devices, serial links, or sensors transmitting bytes per second
-
Describing storage input/output or backup transfer rates using SI prefixes
-
Emulating or comparing legacy modem speeds for vintage computing or protocol testing
-
Documenting old telemetry or serial links with low bit rate increments
Tips & Best Practices
-
Ensure you understand that kilobyte/second uses SI decimal units (1000 bytes) while modem speed is bit-based
-
Use the conversion to relate modern byte-oriented rates with the legacy bit-based modem standards
-
Apply the converter cautiously, knowing that real modem speeds might vary due to analog signaling and legacy constraints
-
Use examples as a guide when estimating data transfer rates in historical or technical contexts
Limitations
-
The modem speed is a nominal approximate rate of 110 bits per second and may not reflect real-world variations
-
Kilobyte/second uses decimal units, while modem speeds measure bits, so throughput comparisons require careful interpretation
-
The conversion is fixed and does not adjust for different signaling methods or variations in modem technology
Frequently Asked Questions
-
What does kilobyte/second (SI def.) mean?
-
It is a data transfer rate equal to 1000 bytes per second, representing how many bytes move each second using decimal prefixes.
-
What is modem (110) in data transfer?
-
Modem (110) refers to a legacy modem speed of about 110 bits per second used in early dial-up and teletype communication systems.
-
Why convert kilobyte/second to modem (110)?
-
Users convert to relate modern transfer rates measured in bytes per second to old legacy communication speeds in bits per second, useful for comparisons, emulation, or documenting vintage systems.
Key Terminology
