About Data Units

Digital data measures information storage and transmission. The base unit is the bit (binary digit, 0 or 1), with 8 bits making 1 byte — the smallest addressable unit in modern computing. This converter handles all major data units: bytes and decimal multiples (kilobyte = 1,000 B, megabyte = 10⁶ B, gigabyte = 10⁹ B, terabyte = 10¹² B, petabyte = 10¹⁵ B used by storage manufacturers), and binary multiples (KiB = 1,024 B, MiB, GiB, TiB used by operating systems — the source of the famous '1 TB drive shows 931 GB free' discrepancy). Network speeds use bits per second multiples (Mbps = megabits per second, Gbps): note that 100 Mbps internet equals 12.5 MB/s download speed because 1 byte = 8 bits. Use data conversion for storage capacity, file sizes, network bandwidth, mobile data plans, and cloud-storage planning. Modern smartphones store tens to hundreds of GB; large data centers manage petabytes.

Popular Data Conversions

Most-used tools

Bit (b) Conversions

About Bit

The bit is the smallest unit of digital information, used in network speeds and information-theory calculations.

Byte (B) Conversions

About Byte

The byte equals 8 bits and is the smallest addressable storage unit in modern computing and digital systems.

Kilobyte (KB) Conversions

About Kilobyte

The kilobyte equals 1,000 bytes and was the standard file size for documents and programs in early computing.

Megabyte (MB) Conversions

About Megabyte

The megabyte is the everyday unit for image files, songs, and small documents on personal computers.

Gigabyte (GB) Conversions

About Gigabyte

The gigabyte is the standard unit for smartphone storage, mobile data plans, and modern application sizes.

Terabyte (TB) Conversions

About Terabyte

The terabyte is the standard unit for hard drives, video archives, and consumer cloud-storage subscriptions.

Petabyte (PB) Conversions

About Petabyte

The petabyte rates large data centers, scientific archives, and major social-media storage systems worldwide.

Megabit per Second (Mbps) Conversions

About Megabit per Second

Megabits per second is the standard unit for internet speeds, network bandwidth, and ISP connection ratings.

Data Conversion Tips

  • 8 bits = 1 byte. Storage usually quoted in bytes; network bandwidth in bits.
  • 1 KB is ambiguous: 1000 bytes (SI) in networking and drives, 1024 bytes (binary) in RAM and OS.
  • A 1 Gbps connection transfers ~125 MB/s (divide Mbps by 8 to approximate MB/s).
  • File sizes: MB usually 1024 KB in OS, 1000 KB on disc packaging.

Common Data Mistakes

  • Confusing bits (b) and bytes (B) — 8× difference.
  • Assuming 1 GB drive holds 1 billion bytes — OS-formatted shows less (binary interpretation).
  • Mixing Mbps (network) with MB/s (file transfer) — factor of 8.
  • Ignoring compression and overhead in real-world transfer speeds.
