How Long to Upload 5 GB at 10 Mbps?

With a 10 Mbps upload connection, a 5 GB file takes approximately 1h 8m 16s under ideal conditions.

Why does a 5 GB upload take 1h 8m 16s at 10 Mbps?

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 5 GB (5,120 MB) at 10 Mbps: 5,120 MB × 8 ÷ 10 Mbps = 4,096 seconds ≈ 1h 8m 16s

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 1h 25m 20s. If you're on Wi-Fi instead of Ethernet, expect even longer due to signal interference.
