What is Data Converter?

A data converter transforms measurements between different digital storage units, including bits, bytes, kilobytes, megabytes, gigabytes, terabytes, and beyond. Whether you're managing file sizes, comparing storage plans, or understanding internet speeds, accurate data unit conversions are essential in our digital world.

Digital storage uses two measurement systems: the decimal system (base 10, used by storage manufacturers) and the binary system (base 2, used by operating systems). This difference explains why a 500 GB hard drive shows only about 465 GB in your computer. Understanding these conversions helps you make informed decisions about storage purchases and data management.

Formula

Binary (used by OS):

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

Decimal (used by manufacturers):

1 KB = 1,000 bytes

1 MB = 1,000 KB

1 GB = 1,000 MB

1 TB = 1,000 GB

Example

A 4K movie file of 15 GB equals 15,360 MB or 15,728,640 KB. In binary terms, it's approximately 13.97 GiB. A USB drive advertised as 64 GB actually provides about 59.6 GiB of usable space in your operating system.

Frequently Asked Questions

Why does my hard drive show less space than advertised?

Manufacturers use decimal (1 GB = 1 billion bytes) while operating systems use binary (1 GiB = 1,073,741,824 bytes). A 1 TB drive shows about 931 GiB in Windows.

What's the difference between bits and bytes?

A byte is 8 bits. Internet speeds are measured in bits per second (Mbps), while file sizes are in bytes (MB). A 100 Mbps connection downloads about 12.5 MB per second.
