Internet Speed Calculator
Calculate download times and convert between internet speed units like Mbps and MB/s.
Download Time
409.6 sec
Download Time vs Connection Speed
Formula
## 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)**
Exemplo Resolvido
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
Perguntas Frequentes
Why is Mbps different from MB/s?
Mbps is megabits per second, MB/s is megabytes per second. Since 1 byte = 8 bits, divide Mbps by 8 to get MB/s. ISPs use Mbps because the number looks bigger.
Why are my actual speeds slower than advertised?
Advertised speeds are theoretical maximums. Wi-Fi interference, network congestion, distance from router, and server limitations all reduce actual speeds.
What speed do I need for streaming?
HD streaming needs about 5 Mbps, 4K needs 25 Mbps, and online gaming needs 10-25 Mbps with low latency. Multiple users need proportionally more.
