Link-time lower bound
Convert a decimal file size and a stated link rate into an ideal transfer-time lower bound. This is not a measured speed or completion-time prediction.
Seconds = decimal GB × 8 ÷ Gbit/s. GB means one billion bytes; GiB is different. Protocol overhead, storage speed, shared traffic and encoding reduce effective throughput.Keyboard and mouse space
Enter measured widths in millimetres. The result is a one-dimensional budget, with no claim about posture, comfort, depth, cable clearance or the suitability of a particular desk.
Remaining width = desk − keyboard − chosen mouse zone − other gaps. The example keyboard width is a documented MX Keys S dimension; the desk and movement-zone amounts are hypothetical.Peripheral purchase total
Enter actual seller-quoted amounts once. The preset amounts are hypothetical arithmetic examples, not current prices. Tax is an entered amount, not an assumed legal rate.
Products + required accessories + delivery + entered tax. Compare warranty, return eligibility, return shipping, receiver inclusion and power supplies separately; an unknown charge is not zero.
