Frequently Asked Questions
How do I calculate download time?
To calculate download time, divide the file size (in bits) by your connection speed (in bits per second). For example, a 1 GB file on a 100 Mbps connection: 1 GB = 8,000 Mb, so 8,000 / 100 = 80 seconds. Our calculator handles all the unit conversions automatically — just enter the file size and your speed.
What is the difference between Mbps and MB/s?
Mbps (megabits per second) measures network speed in bits, while MB/s (megabytes per second) measures data transfer in bytes. Since 1 byte = 8 bits, divide Mbps by 8 to get MB/s. For example, 100 Mbps = 12.5 MB/s. ISPs advertise in Mbps, while file downloads often show MB/s.
How much bandwidth do I need for streaming?
Bandwidth needs depend on quality: SD video requires about 3 Mbps, HD (720p) needs 5 Mbps, Full HD (1080p) needs 8 Mbps, 4K needs 25 Mbps, and 8K needs 50 Mbps. For a household with multiple simultaneous streams, add the requirements together. A 100 Mbps connection can support about 4 simultaneous 4K streams.
