Data & Bandwidth Unit Converter
Convert between Mbps, Gbps, MB/s, GB/s, and calculate file download duration across network connection speeds.
Converting Network Throughput & Download Times
Network bandwidth is measured in bits per second (bps, Mbps, Gbps), whereas stored file sizes are measured in bytes (B, MB, GB). One byte equals 8 bits.
Understanding the 8:1 ratio between bits and bytes clarifies why a 100 Mbps broadband connection downloads data at a peak speed of 12.5 MB/sec.

Data & Bandwidth Unit Converter Engineering FAQs
Why does a 1 Gbps fiber connection not download at 1,000 MB/sec?
1 Gbps equals 1,000 Megabits per second. Dividing by 8 bits per byte gives a theoretical maximum transfer rate of 125 Megabytes (MB) per second.
What network protocol overhead should be subtracted from raw bandwidth?
TCP/IP header overhead, Ethernet framing, and TCP windowing reduce usable payload throughput by approximately 3% to 5%.
What is the difference between Megabytes (MB) and Mebibytes (MiB)?
Megabytes use decimal notation (10^6 = 1,000,000 bytes), while Mebibytes use binary notation (2^20 = 1,048,576 bytes).
