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).
