Digital Data Converter
Convert between bytes, KB, MB, GB, TB, and binary units
Conversion Formula
Target = Value × (From Ratio / To Ratio)
Digital data conversions use linear ratios. Target = Value × (Source Ratio / Target Ratio). To convert megabytes to gigabytes: multiply by 8,000,000 / 8,000,000,000.
Digital data conversion is essential for understanding file sizes, storage capacity, and bandwidth. Convert between bits, bytes, kilobytes, megabytes, gigabytes, terabytes, petabytes, and binary prefixes (KiB, MiB, GiB, TiB).
Binary prefixes (KiB, MiB, GiB) use multiples of 1,024, while decimal prefixes (KB, MB, GB) use multiples of 1,000. This converter supports both systems.
All Supported Digital Data Units
| Unit | Symbol | Definition |
|---|---|---|
| Bit | bit | The fundamental unit of digital information, representing a binary 0 or 1. |
| Byte | B | A unit of digital information equal to 8 bits, the standard for data sizes. |
| Kilobyte | KB | One thousand bytes (decimal), used for file size labeling. |
| Megabyte | MB | One million bytes (decimal), used for documents and images. |
| Gigabyte | GB | One billion bytes (decimal), used for storage capacity ratings. |
| Terabyte | TB | One trillion bytes (decimal), used for hard drive and cloud storage. |
| Petabyte | PB | One quadrillion bytes, used for data center and big data storage. |
| Kibibyte | KiB | 1,024 bytes (binary), used in operating systems for file sizes. |
| Mebibyte | MiB | 1,048,576 bytes (binary), used in computing for memory and storage. |
| Gibibyte | GiB | 1,073,741,824 bytes (binary), the true capacity in computer systems. |

Frequently Asked Questions
KB (Kilobyte) = 1,000 bytes (decimal). KiB (Kibibyte) = 1,024 bytes (binary). Hard drive manufacturers use decimal; operating systems use binary.
The decimal system (1,000) is SI-standard. The binary system (1,024) is used in computing because memory is addressed in powers of 2. This causes the discrepancy in reported storage sizes.
In the decimal system, 1 GB = 1,000 MB. In the binary system, 1 GiB = 1,024 MiB. This converter supports both systems for accuracy.
A bit is the smallest unit of digital data (0 or 1). A byte is 8 bits. Internet speeds are typically measured in bits per second (Mbps), while file sizes are in bytes (MB, GB).
In the decimal system, 1 TB = 1,000 GB. In the binary system, 1 TiB = 1,024 GiB. Modern hard drives are typically rated in decimal TB.
A petabyte (PB) equals 1,000 TB or 1 quadrillion bytes. It is used for data center capacity, cloud storage infrastructure, and big data analytics by major tech companies.
To convert megabits per second to megabytes per second, divide by 8. For example, 100 Mbps ÷ 8 = 12.5 MB/s. This is crucial for understanding actual download speeds.
