The data transfer rate converter changes the units of an entered rate. The data usage calculator combines entered activity hours and counts with publisher-defined rates to estimate a monthly amount. A rate and an amount are different inputs.
| Feature | Rate converter | Data usage |
|---|---|---|
| Editable inputs | Value, From, To | Activity hours/counts, quality choices, optional data limit |
| Time basis | Per second | Entered monthly activity totals |
| Main operation | Rate × source factor ÷ target factor | Sum activity amounts from built-in rates |
| Primary | Selected rate unit | Monthly GB, fixed 2 fractional places |
| Supporting results | Other unselected rate units | Activity totals; limit percentage only when limit > 0 |
The rate form defaults to 100 Mbit/s → 0.100 Gbit/s. Choosing GB/s instead gives raw 0.0125 and displays 0.013 GB/s. There is no file-size or elapsed-time control, so the form does not calculate transfer duration or actual monthly consumption.
The usage default displays 4.70 GB. Its hours, quality choices and counts are editable, while rates such as a game-download allowance of 50 GB are publisher assumptions, not measurements of the user’s services. A worked scenario enters 20 HD-video hours, 30 high-quality-music hours, 15 gaming hours, one game download, eight HD-call hours, 25 mixed-web hours, 20 social hours, 40 photos and ten videos. The sum is 101.95 GB under those rules.
With a 100 GB entered limit, the worked scenario’s arithmetic ratio is 101.95%. The panel, note and Copy display 102.0%, rounded to one fractional place. Entering 0 for the limit omits the percentage; it does not change the activity total. The >90% result tone is a publisher rule, not a provider’s billing policy.
Choose by what you know: an amount per second for unit conversion, or activity inputs for the monthly estimate. Neither calculator measures a connection or establishes a bill, allowance or suitable plan.
