13,000 Photos on a 64 GB Card
With photos averaging 5 MB, a 64 GB card holds 64 × 1,024 ÷ 5 ≈ 13,100 shots — enough for a long trip, and the arithmetic that turns an abstract capacity into a concrete count. The classic drive-size surprise runs the other way: a '512 GB' SSD sold on the decimal system holds 512 × 10⁹ bytes, which the binary converter reports as about 476.8 GiB — the missing 35 GB that makes every new drive feel short.
GB versus GiB, and Megabits That Aren't Megabytes
The recurring confusion has two heads. First, binary versus decimal prefixes: 1 GB is 1,024 MB in the binary convention but 10⁹ bytes in the marketing convention, and drive vendors use the bigger one — which is why Windows shows a 1 TB disk as 931 GB. Second, network speeds are megabits (Mb) while storage is megabytes (MB) — a 100 Mbps line moves about 12.5 MB per second, so 'gigabit internet' does not download a gigabyte in a second. File sizes for planning: photos 2-5 MB, HD movies 4-8 GB, 4K movies 25-50 GB, modern games 20-100 GB.
About Data Storage Converter
Storage decisions are unit decisions in disguise: picking between a 512 GB and 1 TB laptop drive, deciding how many 64 GB SD cards a photo trip needs, or sizing an S3 bucket for monthly uploads. Developers and students hit the same conversions from the other side — cache limits quoted in MiB, download quotas in GB, and log sizes that only make sense once converted to the unit the dashboard uses.

FAQs
How many MB in a GB?
1 GB = 1,024 MB. This uses the binary system where each unit is 1,024 times the previous unit, not 1,000.
Why is 1 KB = 1,024 bytes, not 1,000?
Computers use binary (base-2) system. 1,024 = 2^10, which is the closest power of 2 to 1,000. This is the standard in computing.
How much storage do I need?
It depends on usage. Photos: 2-5 MB each. HD movies: 4-8 GB each. 4K movies: 25-50 GB each. Games: 20-100 GB each. Plan accordingly.
