Frequently Asked Questions
Is this using binary (1024) or decimal (1000) units?
This converter uses binary units where 1 KB = 1,024 bytes. This is the standard for operating systems and file sizes.
Why do hard drive manufacturers use decimal?
Hard drive makers use decimal (1 KB = 1,000 bytes) which makes drives appear larger. A 1 TB drive is actually about 931 GB in binary.
What is a petabyte?
A petabyte (PB) is 1,024 terabytes or about 1 million gigabytes. Large data centers and cloud storage providers work at this scale.
