Frequently Asked Questions
What's the difference between Mbps and MB/s? â–¼
Mbps (megabits per second) measures data in bits, while MB/s (megabytes per second) measures in bytes. Since 1 byte = 8 bits, you divide Mbps by 8 to get MB/s. For example, 100 Mbps = 12.5 MB/s. ISPs advertise in Mbps, but download managers show MB/s.
Why does my download speed look lower than what my ISP advertises? â–¼
Two reasons: First, ISPs use Mbps while downloads show MB/s (divide by 8). Second, real speeds are affected by network congestion, server limits, Wi-Fi interference, and distance from router. Expect 70-90% of advertised speeds in practice.
What unit should I care about when downloading games? â–¼
Focus on MB/s since that's what Steam, Epic, and other platforms display. A 100 Mbps connection gives you about 12.5 MB/s. A 50 GB game at 12.5 MB/s takes roughly 67 minutes to download.
