Binary (IEC) units use powers of 1024: 1 KiB = 1024 bytes, 1 MiB = 1024² bytes, 1 GiB = 1024³ bytes. Decimal (SI) units use powers of 1000: 1 KB = 1000 bytes, 1 MB = 1000² bytes, 1 GB = 1000³ bytes. This distinction matters because a "1 TB" hard drive using decimal units actually contains about 909 GiB of binary storage. IEC units (KiB, MiB, GiB, TiB) were created in 1998 by the International Electrotechnical Commission to eliminate this confusion.

Frequently Asked Questions
In decimal (SI) units: 1 TB = 1,000,000,000,000 bytes (10¹²). In binary (IEC) units: 1 TiB = 1,099,511,627,776 bytes (2⁰). The difference is about 10%, which is why a "1 TB" drive shows as ~909 GB in your operating system. This converter handles both systems accurately.
The largest officially recognized SI unit is the Yottabyte (YB) = 10²⁴ bytes. Beyond that, the International Electrotechnical Commission has proposed the Ronnabyte (RB) = 10²⁷ bytes and Quettabyte (QB) = 10³ bytes. In binary, the largest is Yobibyte (YiB) = 2⁸⁰ bytes ≈ 1.2 × 10²⁴ bytes. For context, the entire internet is estimated to contain about 120 zettabytes of data.
Hard drive manufacturers use decimal (SI) units where 1 TB = 1,000,000,000,000 bytes. However, operating systems like Windows use binary units where 1 GiB = 1,073,741,824 bytes. So 1,000,000,000,000 ÷ 1,073,741,824 = 931.32 GiB. This is not a defect — it's just different measurement systems. macOS uses decimal units and would show the full 1 TB.
A nibble (also spelled nybble) is 4 bits, or half a byte. It can represent 16 values (0-15 in decimal, 0-F in hexadecimal). The term was coined in the 1970s as a play on "byte" — just as a bite is half a byte, a nibble is half a byte. Nibbles are commonly used in hexadecimal notation and low-level programming.
Historical media: 8-inch floppy (80 KB), 5.25-inch floppy (360 KB-1.2 MB), 3.5-inch floppy (1.44 MB), Zip disk (100-250 MB), Jaz disk (1-2 GB).
Optical media: CD (700 MB), DVD (4.7-17 GB), Blu-ray (25-128 GB).
Modern media: USB drives (8 GB-2 TB), SD cards (16 GB-1 TB), SSDs (128 GB-8 TB), HDDs (500 GB-20 TB).
Enterprise: Tape drives (up to 18 TB per cartridge), NAS systems (up to petabytes).
Optical media: CD (700 MB), DVD (4.7-17 GB), Blu-ray (25-128 GB).
Modern media: USB drives (8 GB-2 TB), SD cards (16 GB-1 TB), SSDs (128 GB-8 TB), HDDs (500 GB-20 TB).
Enterprise: Tape drives (up to 18 TB per cartridge), NAS systems (up to petabytes).
A bit (binary digit) is the smallest unit of data and can hold a value of 0 or 1. A byte consists of 8 bits and can represent 256 different values (0-255). Storage capacity is typically measured in bytes, while network transfer rates are measured in bits per second. This is why a 100 Mbps internet connection downloads at about 12.5 MB/s (100 ÷ 8 = 12.5).
Yes! Our converter includes a Network Transfer Rates category that converts between bits per second (bps), kilobits per second (Kbps), megabits per second (Mbps), gigabits per second (Gbps), and terabits per second (Tbps). Note that these measure speed (data per time), not storage capacity. To convert to storage, you'd need to multiply by time (e.g., 100 Mbps × 60 seconds = 6000 megabits = 750 megabytes).
