Limitations
- Uses binary multiples (1 KB = 1,024 bytes). Drive manufacturers use 1,000, so labelled capacities look smaller in an operating system.
- Labels follow KB, MB, GB and TB notation, not KiB, MiB, GiB or TiB. Bits and network speeds such as Mbps are not supported.
- Results show up to 8 decimal places. Values are not rounded during calculation, and a non-zero result that would display as 0 is shown in scientific notation.
