How to use the Byte Unit Converter
This tool converts between common storage units such as Bit, Byte, KB, MB, GB, TB, PB and EB. All units use the binary 1024-based definition (1 KB = 1024 Bytes), and all conversions run entirely in your browser. It is useful for disk capacity estimation, log size statistics, bandwidth estimation and storage planning.
- Type a value into any unit input (decimals are supported). The value is interpreted as a size in that specific unit.
- Once you finish input, all other unit fields will be updated with converted values so you can easily compare Byte, KB, MB, GB, etc.
- Inputs must be numbers greater than or equal to 0. When the input is empty or invalid, the other fields are cleared to avoid confusion.
- The converter uses a strict 1024-based binary system: 1 KB = 1024 Bytes, 1 MB = 1024 KB, 1 GB = 1024 MB, and so on. This matches what most operating systems, programming languages and file systems use for storage capacity.
FAQ
Why use 1024-based units instead of 1000-based units?
Computer memory and most file systems are organized in powers of two, so it is conventional to use 1024-based binary units for KB/MB/GB (for example, 1 KB = 1024 Bytes). Although there are SI decimal units based on 1000 (kB, MB, GB), in development and operations the 1024-based definition is more common.
What is the relationship between Bit and Byte?
1 Byte = 8 Bits. A bit is the smallest unit of information in binary, while a byte is a basic unit for representing characters and larger data structures. This tool lets you convert precisely between Bit and Byte.
How can I use this tool to estimate disk or log sizes?
For example, if one log entry is about 2 KB and you write 100 entries per second, that is about 200 KB per second, 12 MB per minute and 720 MB per hour. You can enter values in KB or MB and quickly see the equivalent GB/TB sizes to evaluate storage requirements.
Are the results suitable for billing or strict accounting?
The converter uses JavaScript floating point arithmetic with rounding for display, which is suitable for capacity estimation and everyday calculations. For billing or strict accounting, you should cross-check with the exact measurement rules of your storage system and verify critical numbers in a backend or specialized numerical environment.
