How upload time is estimated
Upload time equals total file size in bits divided by upload speed in bits per second. This calculator converts your file size (MB or GB) into bits, converts your connection speed (Mbps or MB/s) into bits per second, and divides the two.
Real-world upload speeds are usually somewhat lower than an ISP’s advertised number due to network overhead, server-side limits, and other traffic sharing your connection, so treat this as an optimistic best-case estimate.
