Estimated Time
0s
to transfer 10 GB at 100 Mbps
Note on Real-world Speeds:
Actual transfers are often slower due to network overhead (TCP/IP headers), server latency, and ISP throttling. A safe estimate is often 10-20% slower than the theoretical max.
Planning Large Transfers?
Whether you are migrating a server, backing up 4K video footage, or just downloading a large game, knowing the estimated time helps you plan.
This tool handles the confusing math between bits (speed) and bytes (storage) so you don't have to.
