How long does it take to download 2 GB at 10 Mbps?
26 min 40 sec Theoretical minimum at full line rate (1.25 MB/s), real downloads typically run 5–15% slower. Edit the calculator and this updates live.
Mbps vs MB/s, why the math says 26 min 40 sec
Internet plans are sold in megabits per second (Mbps, small b). File sizes are shown in megabytes (MB, big B). One byte is 8 bits, so a 100 Mbps connection moves at most 12.5 MB of file data per second, divide your plan speed by 8 to get the number your download manager shows.
That factor of 8 is why a "100 meg" plan doesn't download a 100 MB file in one second: it needs 8 seconds in theory, and a little more in practice once protocol overhead (typically 5–15%), Wi-Fi conditions, and server limits are counted.
time = (2 GB × 8 bits/byte) ÷ 10 Mbps = 26 min 40 sec

Frequently asked questions
How long does 2 GB really take at 10 Mbps?
The theoretical minimum is 26 min 40 sec. Real downloads lose 5–15% to protocol overhead, Wi-Fi conditions, and server throttling, so plan on roughly 29 min 20 sec to 30 min 40 sec.
What is 10 Mbps in MB/s?
10 megabits per second equals 1.25 megabytes per second (divide by 8, because one byte is 8 bits). Your download manager reports MB/s, which is why the number looks smaller than your plan speed.
What speed do I need to download 2 GB in under 10 minutes?
At least 27 Mbps of real throughput. Add ~10% headroom for overhead when choosing a plan.
How long would 2 GB take on gigabit (1 Gbps)?
16 sec, about 100× faster than 10 Mbps.
