Bandwidth Reference Guide
Bits vs. Bytes
Network speeds are measured in **Megabits per second (Mbps)**, whereas file sizes are measured in **Megabytes (MB)**. 1 Byte = 8 bits.
Real-World Overhead
Actual transfer rates are typically 80-90% of your maximum provisioned line speed due to TCP/IP header overhead and network congestion.
Throughput Calculation
Download Time = (File Size in Megabits) / (Speed in Megabits per second).
Frequently Asked Questions (FAQ)
Internet service providers advertise speeds in Megabits per second (Mbps), but platforms like Steam display download speeds in Megabytes per second (MB/s). Divide your Mbps speed by 8 to get the maximum expected MB/s rate.
Most streaming services recommend a stable download speed of at least 15 to 25 Mbps for smooth 4K Ultra HD video playback without buffering.
