What does USB data rate refer to in this conversion?

It refers to the nominal link-layer speeds defined by USB standards across various generations, such as 12 Mbit/s to 40 Gbit/s.

Why is T1 (payload) used instead of total T1 line rate?

T1 (payload) represents usable data throughput excluding framing overhead, focusing on actual user-data channels.

Can this converter be used for precise speed measurements?

No, it converts nominal standard rates for comparison but does not account for real-world protocol overhead or hardware factors.

Tips & Best Practices

Verify the USB generation to determine the nominal data rate before conversion
Use the tool to understand differences between modern and legacy data transfer standards
Consider overhead and signaling factors outside the basic payload rate when planning
Apply conversions primarily for planning and comparison, not precise throughput measurement

Limitations

USB speeds vary greatly across versions; conversions reflect nominal rates only
T1 (payload) excludes overhead and signals, representing raw user data throughput
Actual transfer performance can depend on hardware, protocol, and line quality
Conversion is based on static rates, not adjusting to dynamic real-world conditions

Key Terminology

USB: An industry-standard interface for data communication and power delivery between hosts and peripherals, with various generations supporting different nominal data rates.
T1 (payload): The usable data throughput of a North American T1 digital carrier, consisting of 24 channels at 64 kb/s each, totaling 1.536 Mbps excluding framing overhead.
Payload: The portion of a data transmission rate that carries actual user data, excluding overhead such as framing and signaling.
