## How it works

bytes = value × decimal factor (1000^n) or binary factor (1024^n)

## Worked example

1 GB = 1000 MB · 1 GiB = 1074 MB · 1 TB = 1000 GB

## Assumptions

- Inputs are treated as exact decimal values.
- Standard (not historical or survey) unit definitions are used.
- The calculation uses the factors at the precision shown in the formula panel; rounding beyond that is display-only and adds no accuracy.

## Common questions

### Why convert through byte instead of directly?

Routing every unit through a single base (byte) means each unit needs only one exact factor against the standard, and any pair combines cleanly. Direct pair factors drift apart over time in hand-maintained tables; a base-unit graph cannot.

### Where do these exact factors come from?

From published standards (IEC: IEC 80000-13 binary prefixes standard). Units like the inch are defined exactly (1 in = 2.54 cm since 1959), so conversions between standard units are exact, not approximate.

### How precise is the converted data size?

The conversion applies the standard factors shown in the formula panel. The practical limit is your input: the result only regroups the number you entered, so digits beyond the size you started with do not add accuracy. Binary (1024) and decimal (1000) conventions differ, so state which one you mean when the figure matters.

### Why does 1 GiB differ from 1 GB?

1 GB = 10^9 bytes (decimal), 1 GiB = 2^30 bytes (binary). The gap is 7.4% and grows with each prefix step. Standards bodies split the names in 1998 precisely because marketing 'GB' and binary 'GB' had become two different things.
