How long does it take to download 50 GB at 5 Mbps?
22 hr 13 min 20 sec Theoretical minimum at full line rate (0.625 MB/s), real downloads typically run 5–15% slower. Edit the calculator and this updates live.
Mbps vs MB/s, why the math says 22 hr 13 min 20 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 = (50 GB × 8 bits/byte) ÷ 5 Mbps = 22 hr 13 min 20 sec

Frequently asked questions
How long does 50 GB really take at 5 Mbps?
The theoretical minimum is 22 hr 13 min 20 sec. Real downloads lose 5–15% to protocol overhead, Wi-Fi conditions, and server throttling, so plan on roughly 1 day 26 min to 1 day 1 hr 33 min.
What is 5 Mbps in MB/s?
5 megabits per second equals 0.625 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 50 GB in under 10 minutes?
At least 667 Mbps of real throughput. Add ~10% headroom for overhead when choosing a plan.
How long would 50 GB take on gigabit (1 Gbps)?
6 min 40 sec, about 200× faster than 5 Mbps.
