Frequently Asked Questions

A Gigabyte (GB) uses SI decimal prefixes: 1 GB = 1,000,000,000 bytes (10⁹). A Gibibyte (GiB) uses binary prefixes: 1 GiB = 1,073,741,824 bytes (2³⁰). Hard drive manufacturers use GB (decimal), while operating systems like Windows report in GiB, which is why a "500 GB" drive shows as ~465 GiB.

In SI (decimal): 1 MB = 1,000,000 bytes. In binary: 1 MiB (mebibyte) = 1,048,576 bytes (2²⁰). The difference is about 4.86%. Storage manufacturers use the decimal MB, while RAM and OS file sizes typically use the binary MiB convention.

A petabyte (PB) = 10¹⁵ bytes = 1,000 terabytes = 1,000,000 gigabytes. To put this in perspective, 1 PB could store roughly 200 million songs, or 1.5 billion MP3 files. Major data centers store data in petabytes; the internet generates many petabytes of data daily.

Drive manufacturers label capacity using decimal GB (1 GB = 10⁹ bytes), but operating systems report using binary GiB (1 GiB = 2³⁰ bytes = 1.074 × 10⁹ bytes). A 1 TB drive holds 10¹² bytes, which your OS reports as ~931 GiB. This is not missing space — it is a measurement convention difference.

How It Works

Enter Size

Enter the data size. All conversions use the bit as the base unit for maximum precision.

Choose Units

Select from decimal (KB/MB/GB) and binary (KiB/MiB/GiB) units. Both systems are fully supported.

Instant Result

Conversion results appear instantly. The factor shown makes it easy to verify the calculation manually.

Common Use Cases

Storage Planning

Calculate storage requirements for file servers, cloud storage, databases, and backup systems by converting between GB and TB.

Network & Bandwidth

Convert between megabits and megabytes to understand internet speed vs. file size. ISPs rate in Mb/s while files are measured in MB.

Mobile & Apps

Understand app sizes, mobile data usage, and photo/video storage requirements by converting between MB and GB.

Cloud & Hosting

Compare cloud storage plans and hosting quotas by converting between GB and TB to find the best value for your needs.

Video Production

Estimate storage needs for raw video footage — 4K video can use 1–6 GB per minute depending on codec and bitrate.

Software Development

Convert buffer sizes, memory allocations, and file size limits in code between bits, bytes, and larger units.
