Frequently asked questions

Why can the displayed result contain a decimal?

The destination unit may represent a larger amount of data than the source unit. A fractional result is valid for a unit calculation; it does not mean that a file has been split or its storage allocation has changed.

How should I handle rounding?

Keep additional precision during intermediate calculations and round only the final value to suit your task. The formula above is exact; example values marked approximately are shortened for readability. A calculator display can also limit the digits shown.

Does this calculate transfer time?

No. These units describe data quantity. Transfer-time calculations also require a data rate and matching time units.
