Download Time vs Connection Speed
How Internet Speed Relates to Download Time
Internet speed is measured in megabits per second (Mbps), but file sizes are in megabytes (MB). There are 8 bits in a byte.
Formula
Speed (MB/s) = Speed (Mbps) / 8
Download Time (sec) = File Size (MB) / Speed (MB/s)
Example Calculation
Download a 5 GB file on a 100 Mbps connection.
- 01Speed in MB/s = 100 / 8 = 12.50 MB/s
- 02File size in MB = 5 x 1,024 = 5,120 MB
- 03Download time = 5,120 / 12.50 = 409.6 seconds
- 04In minutes = 409.6 / 60 = 6.8 minutes
