About This Tool
Digital storage is measured in binary units where each step is a factor of 1,024 (2¹⁰). This can be confusing because hard drive manufacturers use decimal units (1 GB = 1,000,000,000 bytes) while operating systems report binary units (1 GB = 1,073,741,824 bytes) — which is why a '500 GB' drive shows as roughly 465 GB in your file manager. This converter uses binary calculations (the IEC standard: KiB, MiB, GiB) and supports every unit from individual bits up to petabytes. Essential for developers sizing databases, IT professionals planning storage, and anyone comparing device specifications.

Frequently Asked Questions
How do I convert MB to GB?
Divide the number of megabytes by 1024 (binary) or 1000 (decimal). This converter uses binary calculations where 1 GB = 1024 MB.
Is this data storage converter accurate?
Yes. It uses binary (base-2) calculations: 1 KB = 1024 bytes, 1 MB = 1024 KB, and so on up to petabytes.
Does this converter work on mobile?
Yes. Works seamlessly on phones, tablets, and desktops.
Do I need to sign up to use this tool?
No. Completely free, no account required.
Why does my hard drive show less space than advertised?
Hard drive manufacturers measure in decimal (1 GB = 1,000,000,000 bytes) while operating systems measure in binary (1 GB = 1,073,741,824 bytes). A '500 GB' drive contains 500,000,000,000 bytes, which your OS reports as approximately 465 GiB. This is not missing space — it is a difference in how the same bytes are counted.
What is the difference between Mb and MB?
Lowercase 'b' stands for bits; uppercase 'B' stands for bytes. One byte equals eight bits. Internet speeds are usually quoted in Mbps (megabits per second), while file sizes are usually quoted in MB (megabytes). A 100 Mbps connection transfers approximately 12.5 MB per second.
