Measuring unit for memory

The standard measuring units for memory (digital storage) are based on bytes. Here’s a hierarchy of common memory units:

1. Bit (b) – The smallest unit, represents 0 or 1.
2. Byte (B) – Equals 8 bits.

From there, memory is measured in multiples of bytes:

• Kilobyte (KB) = 1,024 bytes
• Megabyte (MB) = 1,024 KB
• Gigabyte (GB) = 1,024 MB
• Terabyte (TB) = 1,024 GB
• Petabyte (PB) = 1,024 TB
• Exabyte (EB) = 1,024 PB
• Zettabyte (ZB) = 1,024 EB
• Yottabyte (YB) = 1,024 ZB

Note: In some contexts, especially in marketing, 1 KB = 1,000 bytes (decimal system), but in computing, binary measurement (1 KB = 1,024 bytes) is more accurate.
