Frequently Asked Questions
Everything you need to know about our bandwidth calculator
What is the difference between Mbps and MBps?
Mbps = megabits (network), MBps = megabytes (files). 1 MBps = 8 Mbps
Mbps (megabits per second) measures network speed. MBps (megabytes per second) measures file transfer. 1 MBps = 8 Mbps. A 100 Mbps connection transfers 12.5 MBps.
How much bandwidth do I need for streaming?
HD: 5-8 Mbps, 1080p: 10-15 Mbps, 4K: 25-50 Mbps
SD video: 3-4 Mbps. HD (720p): 5-8 Mbps. Full HD (1080p): 10-15 Mbps. 4K: 25-50 Mbps. Add more for multiple simultaneous streams.
How long to download a 1GB file?
10 Mbps: 13 min, 50 Mbps: 2.5 min, 100 Mbps: 1.3 min
At 10 Mbps: ~13 minutes. At 50 Mbps: ~2.5 minutes. At 100 Mbps: ~1.3 minutes. Real speeds vary due to overhead and network conditions.
