Convert between different data storage units including bytes, kilobytes, megabytes, gigabytes and more with precise calculations and instant results.
While a kilobyte is often referred to as 1,000 bytes, in computing it traditionally contains 1,024 bytes (2^10). This difference led to the creation of binary prefixes like kibibyte (KiB) for 1,024 bytes, while kilobyte (KB) now officially represents 1,000 bytes.
A typical high-definition (1080p) movie can range from 4-8 GB in size, while a 4K UHD movie can be 25-100 GB depending on length and compression. Streaming services use advanced compression to reduce these sizes significantly.
In 1956, IBM's first hard disk drive stored just 3.75 MB and weighed over a ton. Today, a microSD card smaller than a fingernail can store up to 1 TB of data—that's over 260,000 times more storage in a fraction of the space.
The world creates approximately 2.5 quintillion bytes of data every day. By 2025, the global datasphere is projected to grow to 175 zettabytes (175 trillion gigabytes), driven by IoT devices, social media, and digital services.
