Why does a 500 GB upload take 5h 41m 20s at 200 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 500 GB (512,000 MB) at 200 Mbps: 512,000 MB × 8 ÷ 200 Mbps = 20,480 seconds ≈ 5h 41m 20s

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 7h 6m 40s. If you're on Wi-Fi instead of Ethernet, expect even longer due to signal interference.
