FAQ

How do I convert KB to bytes?

Multiply by 1000 for decimal or 1024 for binary. For example, 5 KB = 5000 bytes (decimal).

When do I need exact byte counts?

Programming tasks like memory allocation, buffer sizing, and binary file operations require exact byte precision.

What's the difference between KB and KiB?

KB uses 1000 bytes (decimal), while KiB uses 1024 bytes (binary). KiB is technically more accurate for computing.

How many characters fit in 1 KB?

In ASCII, 1000 characters (1 byte each). In UTF-8, it varies as some characters use multiple bytes.
