Understanding Bandwidth & Data
Bandwidth is the maximum rate of data transfer across a network, measured in bits per second (bps). File sizes, on the other hand, are almost always measured in bytes. Confusingly, 1 byte equals 8 bits, so a 100 Mbps connection downloads at a maximum of only 12.5 MB/s — a gap that trips people up every time a download bar seems to crawl slower than their plan promised.
Key Formulas
Transfer time (seconds) = File size (bits) / Speed (bps) File size in bits = File size (MB) x 8 x 1,000,000 1 byte = 8 bits 1 MB = 1,000,000 bytes (decimal) or 1,048,576 bytes (binary / MiB) 1 GB = 1,000 MB = 1,000,000,000 bytes 100 Mbps = 100,000,000 bps = 12.5 MB/s Speed in MB/s = Speed in Mbps / 8
