よくある質問

How do I calculate download time?

ダウンロード time = (File Size in bits) / (Network Speed in bits per second). First convert your file size to bits (multiply by 8), then divide by your network speed in bps. 当社の計算機 does this automatically for any units you choose.

Why is the realistic time longer than the theoretical time?

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

What is the difference の間 MB/s と Mbps?

MB/s (megabytes per second) と 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計算機 free to use?

はい, completely free. いいえ ads, no registration, no limits. すべて calculations happen in your browser.
