![]() Only when one buys a RAM module nowadays it will still have a size that is closely related to some power of two. Because 2 10 = 1024, pretty close to 1000, 1024 bytes were referred to as a ‘kilobyte’ and similarly for ‘megabyte’ etc.įor the average user however the relevance of units tailored to grids of memory cells is null. Especially in early computer systems, memory and hard disk sizes were often exact multiples of powers of two due to the way the underlying hardware was constructed. There was a valid reason why these weird units were used. Until the year 2000, when someone said one megabyte, in nearly all cases an actual value of 2 20, or 1048576 bytes was meant. Why Can “Megabyte” Mean Two Different Things? They are the ‘zettabyte’ (‘zebibyte’) and ‘yottabyte’ (yobibyte) respectively. In case you are wondering: yes, two larger units after exabyte (exbibyte) exist. Check “Round Up” as well to round every number up to the smallest integer that is large enough to contain the actual value. ![]() The powers of 10 and 2 next to the input boxes are multipliers to obtain the number of bytes.Ĭheck “Round Values” to round all numbers to 2 digits after the decimal point. ![]()
