What is the difference between MB and MiB?

MB (decimal megabyte) = 1,000,000 bytes. MiB (binary mebibyte) = 1,048,576 bytes. Disk manufacturers often use decimal; operating systems may display binary.

Why does my 1 TB drive show ~931 GB?

Marketing uses 1 TB = 1,000 GB (decimal). The system may report in binary GiB, resulting in a smaller number on screen.

Is the conversion accurate?

Yes, we use factors of 1000 (decimal) and 1024 (binary) according to the standard selected in the interface.

Do I need to install anything?

No. Just open the page in your browser on any device.

Does it work for internet speed (Mbps)?

This tool converts storage (bytes). Speed uses bits per second — a different unit.

About this tool

Bytes, kilobytes, megabytes, and gigabytes appear in downloads, phone storage, hosting plans, and backups. The most common confusion is the difference between the decimal standard (1 KB = 1,000 bytes, used by disk manufacturers and carriers) and the binary standard (1 KiB = 1,024 bytes, common in operating systems and RAM).

The MyWebTools converter shows both standards side by side. You enter a value, choose the source unit, and instantly see the conversion to bytes, KB, MB, GB, and TB. Everything runs in your browser with no data upload.

If you have ever wondered why a "1 TB" drive shows less free space in Windows, or why a 100 MB file on a website weighs differently on macOS, this tool helps you translate between units correctly.

How to convert digital units

Enter the numeric value. Type the size you want to convert (e.g. 500, 1.5, 1024).
Select the source unit. Choose whether the value is in bytes, KB, MB, GB, or TB.
Compare decimal and binary. See results in both standards to understand label differences between manufacturers and operating systems.
Use the correct value in context. Internet plans and SSDs often use decimal; partitions and RAM use binary.

When to use this tool

Calculate space needed for backup or video upload.
Compare web hosting plans (disk and bandwidth).
Understand cloud storage bills (AWS S3, Google Drive, etc.).
Convert image and PDF sizes for email attachment limits.
Study computer science and networking with practical examples.
