What Is a Digital Converter?

A digital converter is a free tool that converts between digital data and storage units.

Supported Units

  • Bit — Smallest unit. 0 or 1.
  • Byte — 8 bits. Basic storage unit.
  • Kilobyte — Decimal: 1000. Binary: 1024.
  • Megabyte — Decimal: 1M bytes.
  • Gigabyte — Decimal: 1B bytes.
  • Terabyte — Decimal: 1T bytes.
  • Petabyte — Decimal: 1Q bytes.

How Does Digital Converter Work?

Decimal: 1 KB = 1000 bytes. Binary: 1 KiB = 1024 bytes. Manufacturers use decimal; OS may use binary.

How to Use This Tool

  1. Enter a numeric value — Type the measurement you want to convert.
  2. Select the source unit — Choose the unit you are converting from.
  3. Read the results — The tool instantly displays equivalents in every supported unit.
