What is the difference between a Kilobyte (KB) and a Kibibyte (KiB)?

A Kilobyte (KB) is based on the decimal system and equals 1,000 bytes. A Kibibyte (KiB) is based on the binary system and equals 1,024 bytes (2^10). This distinction is critical for accurate memory and storage calculations.

Why does my 1TB hard drive show up as 931GB in Windows?

Hard drive manufacturers use decimal units (1 TB = 1,000,000,000,000 bytes), but Windows calculates storage using binary units (TiB). 1,000,000,000,000 bytes divided by 1,024^3 equals approximately 931 GiB.

Is this tool safe to use with sensitive infrastructure data?

Yes. The converter performs all calculations on the client side (in your browser). No data is sent to any server, ensuring your infrastructure details remain private.

Which unit should I use for network speeds?

Network speeds (like Mbps or Gbps) are almost always measured using the decimal (SI) system. You should use the decimal conversion setting for these calculations.

Does the converter support very large units like Yottabytes?

Yes, the tool supports a wide range of units from bytes up to Petabytes and Exabytes, covering almost all practical modern computing requirements.

Convert Bytes, Binary Units, and Decimal Units

Convert storage and data quantities between bytes, kilobytes, megabytes, gigabytes, terabytes, and larger units. The important choice is whether the calculation uses powers of 1,000 or powers of 1,024.

Decimal and binary units

Decimal: 1 kB = 1,000 bytes and 1 MB = 1,000,000 bytes. Storage vendors commonly use this convention.
Binary: 1 KiB = 1,024 bytes and 1 MiB = 1,048,576 bytes. Operating systems and memory tools often use this convention.

For transfer speeds, distinguish bits from bytes: 8 megabits per second equals 1 megabyte per second before protocol overhead. Use the unit labels shown by the converter when comparing disk capacity, memory, download speed, or upload limits.
