About this calculator
Whether downloading a 100 GB video game, backing up a database to cloud storage, or transferring 4K video footage, knowing exact transfer durations prevents unexpected downtime.
This tool calculates theoretical and real-world transfer times (accounting for 10% TCP/IP packet overhead and network jitter) across gigabits, megabits, megabytes, and gigabytes.
How It Works & Formula
Converts file size to total bits (1 Byte = 8 bits, 1 GB = 8,000,000,000 bits in decimal network metrics). Transfer Time (seconds) = (File Size in bits) / (Bandwidth Speed in bits per second).
