                A <strong>data storage unit</strong> indicates how much digital
                information a device can hold or a file occupies. The
                <strong>byte</strong> is the fundamental unit used by operating
                systems, databases and file systems to report sizes. Above the
                byte, we have larger units such as kilobytes, megabytes,
                gigabytes and terabytes.

              <h3>Decimal vs binary prefixes (KB vs KiB)</h3>
              <p>
                Confusion often comes from the fact that there are
                <strong>two different prefix systems</strong> in use:
              </p>
              <ul>
                <li>
                  <strong>Decimal (SI) prefixes</strong> – powers of 10:
                  <br />
                  1 KB = 1,000 bytes, 1 MB = 1,000,000 bytes, 1 GB =
                  1,000,000,000 bytes, etc.
                </li>
                <li>
                  <strong>Binary (IEC) prefixes</strong> – powers of 2:
                  <br />
                  1 KiB = 1,024 bytes, 1 MiB = 1,048,576 bytes (2<sup>20</sup>),
                  1 GiB = 1,073,741,824 bytes (2<sup>30</sup>), etc.
                </li>
              </ul>
              <p>
                Hardware vendors generally prefer
                <strong>decimal units</strong> (because they look larger), while
                many operating systems still report capacities using
                <strong>binary units</strong>. The calculator on this page makes
                the distinction explicit and converts between both worlds.
              </p>

              <h2>Conversion formulas used by the calculator</h2>
              <p>
                All conversions are performed via a neutral base unit: the
                <strong>byte</strong>. Each supported unit has a
                <em>factor</em> that expresses how many bytes it contains.
              </p>

              <div class="formula-box text-sm">
                <p class="font-semibold mb-1">General conversion logic</p>
                <p class="mb-1">
                  Let <em>v</em> be the original value,
                  <em>k<sub>from</sub></em> the byte factor of the source unit,
                  and <em>k<sub>to</sub></em> the byte factor of the target
                  unit.
                </p>
                <p class="mb-0">
                  <code>bytes = v × k_from</code><br />
                  <code>result = bytes ÷ k_to</code>
                </p>
              </div>

              <h3>Typical factors (decimal)</h3>
              <ul>
                <li>1 KB = 1,000 bytes</li>
                <li>1 MB = 1,000,000 bytes</li>
                <li>1 GB = 1,000,000,000 bytes</li>
                <li>1 TB = 1,000,000,000,000 bytes</li>
                <li>1 PB = 1,000,000,000,000,000 bytes</li>
              </ul>

              <h3>Typical factors (binary)</h3>
              <ul>
                <li>1 KiB = 1,024 bytes</li>
                <li>1 MiB = 1,048,576 bytes (2<sup>20</sup>)</li>
                <li>1 GiB = 1,073,741,824 bytes (2<sup>30</sup>)</li>
                <li>1 TiB = 1,099,511,627,776 bytes (2<sup>40</sup>)</li>
                <li>1 PiB = 1,125,899,906,842,624 bytes (2<sup>50</sup>)</li>
              </ul>

              <h2>Practical examples</h2>
              <h3>Example 1 – Convert 500 GB to GiB</h3>
              <ol>
                <li>
                  Express 500 GB in bytes: 500 × 1,000,000,000 = 500,000,000,000
                  bytes.
                </li>
                <li>Divide by 1 GiB = 1,073,741,824 bytes.</li>
                <li>500,000,000,000 ÷ 1,073,741,824 ≈ 465.66 GiB.</li>
              </ol>
              <p>
                This is why a “500 GB” disk often shows as around 466 GiB in
                your operating system.
              </p>

              <h3>Example 2 – Convert 32 GiB to GB</h3>
              <ol>
                <li>
                  Express 32 GiB in bytes: 32 × 1,073,741,824 ≈ 34,359,738,368
                  bytes.
                </li>
                <li>Divide by 1 GB = 1,000,000,000 bytes.</li>
                <li>34,359,738,368 ÷ 1,000,000,000 ≈ 34.36 GB.</li>
              </ol>

              <h2>Good practices when working with data storage</h2>
              <ul>
                <li>
                  Always check whether a document uses decimal or binary
                  prefixes.
                </li>
                <li>
                  When sizing storage systems, specify both the unit and the
                  convention (for example “10 TiB (binary)”).
                </li>
                <li>
                  For SLAs and contracts, use exact byte counts as well as
                  human-readable units to avoid ambiguity.
                </li>
                <li>
                  When comparing hardware from different vendors, normalize all
                  capacities to the same representation using a tool like this
                  converter.
                </li>
              </ul>

                    MB, GB, TB or PB, they are usually decimal. Documentation
                    from vendors or standards bodies should also specify which
