Download Time Formula: Time (seconds) = (File Size in MB × 8) ÷ (Speed in Mbps × Efficiency)
Example: 1GB file (1024 MB) at 100 Mbps with 90% efficiency:
(1024 × 8) ÷ (100 × 0.9) = 8192 ÷ 90 = 91 seconds
Pro Tip: Always divide your internet speed by 8 to get MB/s. 100 Mbps = 12.5 MB/s theoretical max.
