What is a Gigabyte?
A gigabyte (GB) is a unit of digital storage. It measures how much data your computer, phone, or other devices can store. Think of it like a digital container that holds your files, photos, videos, and apps.
One gigabyte equals 1,024 megabytes (MB). This might seem confusing, but computers use binary math. That's why we multiply by 1,024 instead of 1,000 like in regular math.
Quick Facts About Gigabytes:
- 1 GB = 1,024 MB (megabytes)
- 1 GB = 1,048,576 KB (kilobytes)
- 1 GB = 1,073,741,824 bytes
- 1,024 GB = 1 TB (terabyte)

Frequently Asked Questions
Why is 1 GB equal to 1,024 MB and not 1,000 MB?
Computers use binary math (base 2) instead of decimal math (base 10). In binary, we count by powers of 2. So 1 KB = 1,024 bytes, 1 MB = 1,024 KB, and 1 GB = 1,024 MB. This is why storage conversion uses 1,024 instead of 1,000.
What's the difference between GB and GiB?
GB (gigabyte) can mean two things: 1,000,000,000 bytes or 1,073,741,824 bytes. GiB (gibibyte) always means 1,073,741,824 bytes. Our converter uses the binary definition (1,024 MB = 1 GB) because that's what most computers and operating systems use.
How much storage do I need for my phone or computer?
It depends on how you use your device. For basic use (calls, texts, some photos): 64-128 GB is enough. For moderate use (lots of photos, some games): 256-512 GB works well. For heavy use (many games, 4K videos): 1 TB or more is better.
Can I convert between different types of storage units?
Yes! Our gigabyte converter works with all common storage units: bytes, kilobytes (KB), megabytes (MB), gigabytes (GB), terabytes (TB), petabytes (PB), and exabytes (EB). Just select the units you want to convert between.
Is this converter accurate for all file types?
Yes, our converter is accurate for measuring storage space. However, remember that actual file sizes can vary. For example, a "1 MB" photo might actually be 1.2 MB or 0.8 MB depending on the image quality and format.
