How Long to Upload 10 GB at 1 Gbps?

With a 1 Gbps upload connection, a 10 GB file takes approximately 1m 22s under ideal conditions.

Why does a 10 GB upload take 1m 22s at 1 Gbps?

Upload speed is measured in megabits per second (Mbps), while file size is measured in megabytes (MB) or gigabytes (GB). Since 1 byte = 8 bits, you divide your file's size in megabytes by your speed in megabits, then multiply by 8 to get the transfer time in seconds.

For 10 GB (10,240 MB) at 1 Gbps: 10,240 MB × 8 ÷ 1000 Mbps = 82 seconds ≈ 1m 22s

In practice, network overhead, protocol headers, and ISP throttling reduce effective throughput to about 80% of your advertised speed — making the realistic upload time closer to 1m 42s. If you're on Wi-Fi instead of Ethernet, expect even longer due to signal interference.
