Frequently asked questions
Multiply the file size in megabytes by 8 to get megabits, then divide by the speed in Mbps. A 1,000 MB file on a 100 Mbps line takes about 80 seconds.
File sizes are in bytes (MB) but speeds are in bits (Mbps). There are 8 bits in a byte, so the factor of 8 converts between them.
Overheads, server limits, Wi-Fi and shared connections mean you rarely get the full advertised speed, so real times are usually a bit longer.
Mbps is megabits per second; MBps is megabytes per second, which is 8 times larger. This calculator uses Mbps for the connection speed.
