File size in megabytes is multiplied by 8 to get megabits, then divided by your speed in megabits per second and by the efficiency factor. Internet speeds are sold in bits per second, while file sizes are shown in bytes, and there are 8 bits in a byte. That is why a 100 Mbps connection downloads at most 12.5 MB per second.
Example: a 50 GB game on a 100 Mbps connection at 90% efficiency takes about 1 hour 14 minutes.
Wi-Fi signal, other devices on the network, server limits, and protocol overhead all reduce the real speed. 75-90% of the plan speed is common.
Yes. Enter your upload speed instead of your download speed.
