Data Storage Converter Calculator

Work out data storage converter instantly with clear inputs, formula shown and shareable results.

About Data Storage Converter Calculator

Each digital storage unit is defined as a multiple of the byte, so the conversion runs in two steps: multiply by the source unit's factor to reach byte, then divide by the target unit's factor. One factor per unit covers every pair in the list. Decimal prefixes (kB, MB) are powers of 1000 while binary prefixes (KiB, MiB) are powers of 1024, which is why a 1 TB drive shows as about 931 GiB.

Formulas

Two-step conversion

result = value × factor(from) ÷ factor(to)

Base value

base (byte) = value × factor(from)

Worked example

With the default values below, Data Storage Converter Calculator returns Converted Value of 5.000000 × 10⁻¹. Change any input above and every figure here is recalculated in your browser.

Assumptions and limits

The result is derived only from the 3 inputs listed above. Anything not among them is not part of the calculation.
In particular, this calculator does not take inflation, tax, fees or charges or compounding frequency into account.
Figures are rounded for display to 8 decimal places, so totals built from several rounded parts can differ slightly from the unrounded arithmetic.

How these calculators are built and tested is described on the Methodology page. If a figure looks wrong, please report it.

Frequently Asked Questions

Why route through byte?

With 11 units, direct pairs would mean 110 factors to maintain. Going via byte needs one factor per unit and gives the same answer.

Does the dropdown order matter?

Yes. The first is the unit your figure is already in; the second is what you want it in. Swapping them inverts the result.
