Data transfer speed is the number one specification for Internet plans, Wi-Fi routers, and USB drives. But there's a catch: ISPs advertise in bits (Mbps, Gbps), while file sizes are in bytes (MB, GB). Since 1 byte = 8 bits, a '100 Mbps' internet connection can only download at 12.5 MB/s. Our converter handles this 'divide by 8' math for you. It covers everything from 1990s modems (Kbps) to modern fiber optics (Gbps). Common conversions: 1 Gbps = 125 MB/s, and 1 Mbps = 125 KB/s.
