Frequently Asked Questions
How do I calculate download time?▾
Download time = file size (in bits) ÷ connection speed (in bits per second). Our calculator handles unit conversions automatically.
Why is my actual download slower than calculated?▾
Real downloads include protocol overhead, server limitations, and network congestion. Actual speeds are typically 80-90% of theoretical maximum.
