Frequently Asked Questions
Real-world downloads are slower due to network overhead, server limitations, distance, and bandwidth sharing. The calculator shows the theoretical minimum time.
Mbps = Megabits per second (used for internet speed). MBps = Megabytes per second (used for file sizes). 1 byte = 8 bits, so 100 Mbps = 12.5 MB/s.
A 4K movie (~50 GB) on a 100 Mbps connection takes about 67 minutes. On a 1 Gbps connection, it would take about 7 minutes.
