FAQ
How many centimeters in an inch?
One inch equals exactly 2.54 cm — an official international definition, not an approximation.
Is a gigabyte 1024 or 1000 megabytes?
For memory/computing we use 1024 (binary), while storage manufacturers use 1000 (decimal) — that's why a 1TB drive shows less capacity in your system.
