FAQ
Why are Mbps and MB/s different?
Mbps is megabits per second; MB/s is megabytes per second. 1 byte = 8 bits, so 100 Mbps ≈ 12.5 MB/s.
What are SI vs IEC data rates?
SI uses 10³ steps (K, M, G); IEC uses 2¹⁰ steps (Ki, Mi). Both appear in specs. We support both systems.
My ISP advertises Gbps but I see MB/s. Is that normal?
Yes. Many apps show bytes/sec, while ISPs use bits/sec. Divide by 8 to get MB/s from Mbps (and multiply by 8 for the reverse).
How precise are the conversions?
All conversions are exact based on the chosen base (10³ for SI, 2¹⁰ for IEC). Very large/small values may show in scientific notation for readability.
