File & Speed

Speeds use decimal (SI) bits — 1 Mbps = 1,000,000 bits/sec — matching how ISPs advertise them. File sizes use binary (1 GB = 1,073,741,824 bytes).

Pro Tips

  • Bits vs. bytes — the trap. Your ISP advertises megabits (Mb/s), not megabytes. The estimator's presets use real-world numbers, but when typing a custom speed, remember that 100 Mbps is really about 12.5 MB/s.
  • Shave 10% off advertised speeds. Real-world downloads rarely hit the advertised maximum. Knock 10–15% off your plan speed for an estimate that won't betray you.
  • Overhead eats time. Protocol overhead, network congestion, and the server's own limits can all slow things down — treat the estimate as a best-case and add a little buffer for big files.

Your challenge: run the estimator on your current home speed with a 50 GB file, then actually time one big download this week. How close did the Wizard get? Tell us how your prediction stacked up — and keep the Estimator bookmarked for the next giant update.
