File Size Converter Online

Our file size converter uses the standard binary measurement system:

• 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 = 1,099,511,627,776 Bytes
• 1 PB = 1,024 TB = 1,125,899,906,842,624 Bytes

Formula: Result = Value × (From Unit in Bytes) ÷ (To Unit in Bytes)

• help_outline What is the difference between KB and KiB?

  KB (Kilobyte) uses decimal (1 KB = 1000 bytes), while KiB (Kibibyte) uses binary (1 KiB = 1024 bytes). Our converter uses binary, which is standard for file size measurements.

• help_outline How accurate is this converter?

  Our converter uses exact binary calculations (1024 bytes per KB) and rounds to 6 decimal places for display. This provides accurate results for all file size conversions.

• help_outline Can I convert very large file sizes?

  Yes! Our converter handles values up to 1,000,000,000,000,000 (1 quadrillion) bytes accurately.

• help_outline Why use binary instead of decimal?

  Computers use binary (base-2) for data storage. 1 KB = 1024 bytes is the standard measurement used by operating systems and file managers.
