Decimals are accepted, so you can convert a fraction of a unit as well as a whole number.<\/li>\n<li>Choose the unit of that number in <strong>From unit<\/strong>: bit (b), byte (B), Kilobyte (KB), Megabyte (MB), Gigabyte (GB), or Terabyte (TB).<\/li>\n<li>Choose the unit you want in <strong>To unit<\/strong>. You can select the same unit to leave the value unchanged.<\/li>\n<li>Read <strong>Converted Value<\/strong>. The result includes the destination unit and is rounded to six decimal places.<\/li>\n<\/ol>\n<h2>Understanding digital storage units<\/h2>\n<p>A bit is one binary digit; a byte contains eight bits. Their symbols differ only by capitalization: <strong>b<\/strong> means bit, while <strong>B<\/strong> means byte. For example, 8 b equals 1 B, and 8 MB equals 64 million-plus bits under this calculator\u2019s 1024-based definition. Check the letter case before converting a file size or comparing figures from different sources.<\/p>\n<p>The larger units in this converter increase by a factor of 1024: 1024 B equals 1 KB, 1024 KB equals 1 MB, and so on through TB. That makes the default conversion, 1024 KB to MB, equal to exactly 1 MB. Converting toward a larger unit makes the displayed number smaller; converting toward a smaller unit makes it larger. The amount of data itself does not change.<\/p>\n<p>Digital quantities are often used in discussions of files, device capacity, memory, and transfers, but the context affects their meaning. Storage is a quantity, whereas a transfer speed includes a time unit, such as bits per second. This converter changes data units only: it does not calculate how long a transfer takes. If you know a file size and a connection speed, use the <a href=\"https:\/\/wpcalc.com\/en\/converters\/download-speed\/\">Download Time Estimator<\/a> to estimate the time separately.<\/p>\n<h2>Assumptions and practical tips<\/h2>\n<p><strong>KB, MB, GB, and TB have 1024-based meanings here.<\/strong> In formal binary-prefix notation, those sizes are called KiB, MiB, GiB, and TiB. Decimal KB, MB, GB, and TB instead use factors of 1000. The calculator does not offer a decimal mode or separate KiB-style menu options. For instance, its 1 GB equals 1,073,741,824 B, not the 1,000,000,000 B often used to label storage devices. Check which convention a product label or operating system uses before comparing its number with the result.<\/p>\n<p>The result is rounded to six decimal places. A very small nonzero conversion may therefore display as zero, and a rounded result should not be treated as an exact measurement. For a smaller-unit result that is easier to inspect, change <strong>To unit<\/strong> to B or b. Very large values and fine decimal fractions may also be subject to ordinary floating-point precision limits.<\/p>\n<p>Keep quantity and scale separate when reading technical specifications. The <a href=\"https:\/\/wpcalc.com\/en\/converters\/metric-prefix\/\">Metric Prefix converter<\/a> can help with decimal prefixes, but its powers of 1000 are not the powers of 1024 used for KB through TB on this page. If you are working with an image, the <a href=\"https:\/\/wpcalc.com\/en\/converters\/digital-image-resolution\/\">Image DPI &amp; Pixel calculator<\/a> concerns dimensions and resolution; pixel count alone does not determine a compressed image file\u2019s storage size.<\/p>\n<h2>1024-based unit reference<\/h2>\n<table>\n<thead>\n<tr>\n<th>Unit shown<\/th>\n<th>Bytes per unit<\/th>\n<\/tr>\n<\/thead>\n<tbody>\n<tr>\n<td>1 b<\/td>\n<td>0.125 B<\/td>\n<\/tr>\n<tr>\n<td>1 B<\/td>\n<td>1 B<\/td>\n<\/tr>\n<tr>\n<td>1 KB<\/td>\n<td>1,024 B<\/td>\n<\/tr>\n<tr>\n<td>1 MB<\/td>\n<td>1,048,576 B<\/td>\n<\/tr>\n<tr>\n<td>1 GB<\/td>\n<td>1,073,741,824 B<\/td>\n<\/tr>\n<tr>\n<td>1 TB<\/td>\n<td>1,099,511,627,776 B<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n","protected":false},"excerpt":{"rendered":"<p>Convert a value between bits, bytes, KB, MB, GB, and TB using 1024-based storage units.
