What does this tool do?
Broadband speeds are advertised in megabits per second, while downloads are usually shown in megabytes per second. This converter applies the factor of eight and estimates how long a gigabyte takes.
The Formula
MB/s = Mbps ÷ 8; 1 GB transfer time = 1,000 MB ÷ MB/sFrequently Asked Questions
Why is my 100 Mbps connection not downloading at 100 MB/s?
Megabits and megabytes are different units. 100 Mbps is 12.5 MB/s, and protocol overhead, Wi-Fi and server limits reduce the observed speed further.
Are MB and MiB the same?
No. This calculator uses decimal megabytes, where 1 MB = 1,000,000 bytes. A mebibyte (MiB) is 1,048,576 bytes, which is about 4.9% larger.
