Frequently Asked Questions

Find Quick Answers

How do MB and KB relate in this tool?

By default the tool uses 1 MB = 1024 KB and 1 KB = 1/1024 MB. An optional decimal mode switches to 1 MB = 1000 KB. The interface handles both directions to support MB to KB and KB to MB conversions.

Can I convert in decimal mode?

Yes. Decimal mode employs the 1000 multiplier, aligning with decimal storage standards. You can enable this mode to perform MB to KB or KB to MB conversions consistent with decimal data sizing, then revert to binary if needed.

What inputs are considered invalid?

Inputs must be numeric and non-negative. Non numeric values, NaN, or negative numbers trigger an error condition. Extremely large values are handled via floating point arithmetic with standard rounding practices.

Is batch conversion supported?

The tool performs a single value conversion per request. For multiple values, repeat the input entry or automate with separate invocations. Batch processing is not provided in the default form.
