How long does it take to download 10 GB at 200 Mbps?
6 min 40 sec Theoretical minimum at full line rate (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 6 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 = (10 GB × 8 bits/byte) ÷ 200 Mbps = 6 min 40 sec

Frequently asked questions
How long does 10 GB really take at 200 Mbps?
The theoretical minimum is 6 min 40 sec. Real downloads lose 5–15% to protocol overhead, Wi-Fi conditions, and server throttling, so plan on roughly 7 min 20 sec to 7 min 40 sec.
What is 200 Mbps in MB/s?
200 megabits per second equals 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 10 GB in under 10 minutes?
At least 134 Mbps of real throughput. Add ~10% headroom for overhead when choosing a plan.
How long would 10 GB take on gigabit (1 Gbps)?
1 min 20 sec, about 5× faster than 200 Mbps.
