Estimate how long a file takes to download or upload.
A theoretical estimate for downloads or uploads. Protocol overhead, congestion, Wi-Fi and service limits can increase the actual time. MB/GB use powers of 1000; MiB/GiB use powers of 1024.
Example: 1 GB / 100 Mbps = 80 s
Convert bits to bytes and distinguish decimal file sizes from binary units.
Plan for simultaneous activities, upload needs and responsiveness without relying on one universal threshold.
