Bytes Converter
Convert Bytes (B) to any other data storage unit. The table below gives the exact figure for each unit, and every conversion is worked from the same engine as the converter.
What bytes convert to
One B in every other data storage unit.
| Unit | 1 B | Reverse |
|---|---|---|
| Bits | 8 b | 0.125 B |
| Kilobytes | 9.7656e-4 KB | 1,024 B |
| Megabytes | 9.5367e-7 MB | 1,048,576 B |
| Gigabytes | 9.3132e-10 GB | 1,073,741,824 B |
| Terabytes | 9.0949e-13 TB | 1,099,511,627,776 B |
| Petabytes | 8.8818e-16 PB | 1.1259e15 B |
Multiply a bytes figure by the figure in the second column to get the unit in the first, or multiply by the third column to go the other way.
Bytes conversion reference
Bytes to Bits
One bytes is 8 bits, and one bits is 0.125 bytes.
A bit is the smallest unit of digital information: a single 0 or 1. Network speeds and mobile data caps are usually quoted in bits, while file sizes use bytes — eight bits make one byte.
- 1 B= 8 b
- 5 B= 40 b
- 10 B= 80 b
Bytes to Kilobytes
One bytes is 9.7656e-4 kilobytes, and one kilobytes is 1,024 bytes.
This converter treats a kilobyte as 1,024 bytes, the binary value operating systems report. Storage manufacturers often label 1,000 bytes a kilobyte, which is one reason a drive shows less capacity than its label.
- 1 B= 9.7656e-4 KB
- 5 B= 0.004883 KB
- 10 B= 0.009766 KB
Bytes to Megabytes
One bytes is 9.5367e-7 megabytes, and one megabytes is 1,048,576 bytes.
A megabyte here is 1,024 kilobytes. It is used for photos, documents and short audio files; a photo from a phone camera is usually 2 to 5 megabytes.
- 1 B= 9.5367e-7 MB
- 5 B= 4.7684e-6 MB
- 10 B= 9.5367e-6 MB
Bytes to Gigabytes
One bytes is 9.3132e-10 gigabytes, and one gigabytes is 1,073,741,824 bytes.
A gigabyte here is 1,024 megabytes. It is the usual unit for phone storage, mobile data bundles and video; an hour of standard-definition video is roughly a gigabyte.
- 1 B= 9.3132e-10 GB
- 5 B= 4.6566e-9 GB
- 10 B= 9.3132e-9 GB
Bytes to Terabytes
One bytes is 9.0949e-13 terabytes, and one terabytes is 1,099,511,627,776 bytes.
A terabyte here is 1,024 gigabytes. It is used for hard drives, backups and archives; a terabyte holds roughly 250,000 photos or 250 hours of video.
- 1 B= 9.0949e-13 TB
- 5 B= 4.5475e-12 TB
- 10 B= 9.0949e-12 TB
Bytes to Petabytes
One bytes is 8.8818e-16 petabytes, and one petabytes is 1.1259e15 bytes.
A petabyte here is 1,024 terabytes. It is used for data-centre and large-scale storage figures — a single rack of drives can hold several petabytes.
- 1 B= 8.8818e-16 PB
- 5 B= 4.4409e-15 PB
- 10 B= 8.8818e-15 PB
What bytes are used for
A byte is eight bits and normally holds one character of text. It is the base unit for file sizes, memory and storage, and the unit your file manager reports.
Binary and decimal definitions diverge by about 2.4% at kilo and 7.4% at tera. This converter is binary throughout, so it will not match a manufacturer's decimal specification exactly.
A data conversion looks like the metric chain but is not: this converter uses binary steps, so a kilobyte is 1,024 bytes and a megabyte is 1,024 kilobytes, which is what an operating system reports for a file.
The same names are also used in a decimal system of 1,000, and the gap compounds as the units grow. It is why a drive sold at a round decimal capacity shows less in a file manager, and why a bundle described in decimal gigabytes delivers fewer binary gigabytes than the number suggests.
Checking a data conversion means deciding which definition the number came from before doing the arithmetic. A figure of 500 GB is exact under one definition and about 465 GiB under the other, and no amount of rounding makes those the same quantity.
