Convert between Bytes, KB, MB, GB, TB, and PB. Switch between binary (1 KB = 1024 B) and decimal (1 KB = 1000 B). Runs entirely in your browser.
Binary matches most operating systems; decimal matches most drive labels. Rounded for display.
What is a data storage converter? It changes a digital storage amount from one unit (such as megabytes) into every other unit (Bytes, KB, MB, GB, TB, PB), using either binary or decimal steps.
In binary mode each step is 1024: 1 KB = 1024 bytes, 1 MB = 1024 KB, and so on. In decimal mode each step is 1000: 1 KB = 1000 bytes, 1 MB = 1000 KB. Operating systems usually report storage in binary, while drive makers usually advertise in decimal.
In binary mode 1 GB = 1,073,741,824 bytes (1024 × 1024 × 1024). In decimal mode 1 GB = 1,000,000,000 bytes (1000 × 1000 × 1000).
Your value is first converted to bytes using the chosen mode's step size, then divided to every other unit. For example, 1 GB in binary mode becomes 1,073,741,824 bytes, which equals 1024 MB or 1,048,576 KB.
