Mbps to MB-s Converter
Directly translate your internet service provider bitrate into actual Megabytes per second write speed.
Direct Formula: To convert Mbps to MB/s, use Transfer Rate (MB/s) = Advertised Speed (Mbps) / 8. For example, 100 Mbps equals 12.50 MB/s.
How Download Time Is Calculated
Transfer Rate (MB/s) = Advertised Speed (Mbps) / 8Network providers advertise in small "b" bits. File systems measure in capital "B" bytes.
Convert to Bits
Multiply file size in Bytes by 8 to get total bits: 10 GB × 8,000,000,000 bits
Apply Speed & Overhead
Multiply network speed by real-world efficiency (typically 90% due to TCP/IP packet headers): 100 Mbps × 0.90
Divide to Find Duration
Divide total bits by effective throughput: 13 min 20 sec (theoretical) / 14 min 49 sec (with 90% real-world efficiency)
