Understanding Data Transfer Rates

Bits vs Bytes

Internet speeds are typically measured in bits per second (Mbps), while file sizes are usually shown in bytes (MB). There are 8 bits in 1 byte, so 100 Mbps equals 12.5 MB/s.

Real-World Speeds

Actual download speeds are often lower than advertised due to network overhead, congestion, and other factors. Expect roughly 70-90% of your theoretical maximum speed.

Common Conversions

1 Gbps = 1,000 Mbps = 125 MB/s
100 Mbps = 12.5 MB/s
1 MB/s = 8 Mbps
