Data transfer time
Data transfer time lets you estimate transfer time from size, link rate, and efficiency with the formula shown in your browser.
Data unit converter
Data unit converter lets you convert bits, bytes, SI, IEC, capacity, and rate without conflating them in your browser.

How to use
Enter a value and source/target units, distinguishing GB from GiB, bits from bytes, and size from rate.
Read every result with its unit. A size conversion alone cannot determine transfer time; use the transfer-time tool with speed and efficiency for that question.

1Principles and limits
Each input is limited to 1,048,576 bytes, output to 33,554,432 bytes, and processing to 5,000 ms. Input is never silently truncated.
