Data Storage Converter
Convert between digital storage units instantly — bits, bytes, kilobytes, megabytes, gigabytes, terabytes, and petabytes.
About Data Storage Converter
Our Data Storage Converter makes it simple to convert between all common digital storage units. Whether you need to figure out how many megabytes are in a gigabyte, convert kilobytes to bytes, or understand the scale of petabytes, this tool gives you instant, accurate results.
Digital storage is measured in bits and bytes, with each higher unit being 1,024 times the previous one (using the binary system). One kilobyte equals 1,024 bytes, one megabyte equals 1,024 kilobytes, and so on. This converter uses the standard binary definition (1 KB = 1,024 bytes) which is the most common convention in computing.
This tool works entirely in your browser with no data sent to any server. It's perfect for students learning about digital storage, IT professionals calculating disk space, or anyone who needs quick unit conversions for file sizes and storage capacities.
Frequently Asked Questions
Q What is the difference between a kilobyte and a kibibyte?
A kilobyte (KB) traditionally equals 1,024 bytes in computing, while the International System of Units (SI) defines "kilo" as 1,000. To resolve this ambiguity, the term kibibyte (KiB) was introduced to specifically mean 1,024 bytes. However, KB is still widely used to mean 1,024 bytes in most operating systems and software. This converter uses the binary standard (1 KB = 1,024 bytes).
Q How many megabytes are in a gigabyte?
There are 1,024 megabytes in one gigabyte using the binary system. This means a 1 GB file takes up 1,024 MB of storage space. Note that storage manufacturers often use the decimal system (1 GB = 1,000 MB), which is why a 500 GB hard drive may show as about 465 GB in your operating system.
Q What is a petabyte?
A petabyte (PB) is equal to 1,024 terabytes, or approximately 1,125,899,906,842,624 bytes. Petabytes are used to measure extremely large data sets, such as the storage capacity of major cloud services, large-scale scientific databases, or the total data processed by big tech companies. For context, one petabyte can store roughly 500 billion pages of printed text.
