Frequently asked questions
How many MB is 1 GB?
1000 MB in decimal terms, which is what data plans, storage capacities and this converter's MB/GB units use. In binary terms 1 GiB = 1024 MiB, and the converter lists those separately.
How much data does streaming video use?
Roughly 0.7 GB (700 MB) an hour for standard definition, 3 GB an hour for 1080p and 7 GB or more an hour for 4K. Converting to MB is the quick way to see how fast an hour of 4K eats a capped connection.
