📌 Frequently Asked Questions: Binary File Size Calculator

❓ What is a binary file size calculator?

A binary file size calculator is a tool that helps you convert data storage units such as bits, bytes, kilobytes (KB), megabytes (MB), gigabytes (GB), and more using binary base values (1 KB = 1024 bytes).

❓ How is binary different from decimal in file size?

In binary calculations, file sizes are based on powers of 2 (e.g., 1 KB = 1024 bytes), whereas decimal uses powers of 10 (e.g., 1 KB = 1000 bytes). Most operating systems and software use the binary system.

❓ How do I convert bytes to megabytes?

To convert bytes to megabytes in binary, divide the number of bytes by 1,048,576 (1024 × 1024). For example, 1,048,576 bytes equals 1 MB in binary.

❓ Why do file sizes sometimes appear different on Windows vs Mac?

File size differences occur because Windows typically uses binary units (1 KB = 1024 bytes) while macOS may show decimal units (1 KB = 1000 bytes). This can cause discrepancies in displayed file sizes.

❓ Who can benefit from using a binary file size converter?

This tool is useful for developers, IT professionals, students, and anyone needing to accurately calculate or convert file sizes for storage, networking, or software development purposes.
