Frequently Asked Questions

Comment do I calculate download time?

Télécharger time = (File Size in bits) / (Network Speed in bits per second). Premier convert your file size to bits (multiply by 8), then divide by your network speed in bps. Our calculator does this automatically for any units you choose.

Pourquoi is the realistic time longer than the theoretical time?

Real-world network transfers have protocol overhead (TCP/IP headers, handshakes, congestion control) and rarely reach the advertised maximum speed. We add a 10% overhead factor to give you a more practical estimate.

Quoi is the difference between MB/s and Mbps?

MB/s (megabytes per second) and Mbps (megabits per second) measure the same thing but in different units. 1 MB/s = 8 Mbps. Internet providers typically advertise speeds in Mbps, while file downloads often show MB/s.

Is this calculator free to use?

Oui, completely free. Non ads, no registration, no limits. Tout calculations happen in your browser.
