Byte/File Size Converter

Convert between bytes, kilobytes, megabytes, gigabytes, terabytes, and petabytes.

Reference

1 KB = 1,024 Bytes
1 MB = 1,024 KB = 1,048,576 Bytes
1 GB = 1,024 MB = 1,073,741,824 Bytes
1 TB = 1,024 GB
1 PB = 1,024 TB

Why 1024 instead of 1000?

Computers use binary (base-2), so storage is measured in powers of 2. 1 KB = 2^10 = 1,024 bytes.
