How to convert megabytes to gigabytes

To convert megabytes to gigabytes, divide by 1000. For example, 5000 MB ÷ 1000 = 5 GB. Going the other way, multiply gigabytes by 1000 to get megabytes.

Note that computers sometimes use binary units where 1 GiB = 1024 MiB. Hard drive manufacturers use decimal (1 GB = 1000 MB) while operating systems often report in binary (1 GiB = 1024 MiB). This is why a 500 GB hard drive shows as less than 500 GB in Windows.

1 GB = 1000 MB = 1,000,000 KB = 1,000,000,000 bytes (decimal). 1 GiB = 1024 MiB = 1,048,576 KiB = 1,073,741,824 bytes (binary).

Frequently asked questions

How many MB is 1 GB?
1 GB = 1000 MB (decimal). In binary, 1 GiB = 1024 MiB. Hard drives use decimal while operating systems often use binary.
How many GB is 1500 MB?
1500 MB = 1.5 GB. Calculation: 1500 ÷ 1000 = 1.5 GB.
How many MB is 2 GB?
2 GB = 2000 MB. Calculation: 2 × 1000 = 2000 MB.
Why does my hard drive show less space than advertised?
Hard drive makers use decimal (1 GB = 1000 MB) but Windows shows binary (1 GB = 1024 MB). A 500 GB drive contains 500,000 MB but Windows shows it as 465 GB because 500,000 ÷ 1024 = 488 GiB.
How many MB is 5 GB?
5 GB = 5000 MB. Calculation: 5 × 1000 = 5000 MB.
