Quickly and Easily Convert Between Storage Size Units - KB, MB, GB, TB & 512 byte blocks



Quickly and Easily Convert Between Storage Size Units - KB, MB, GB, TB & 512 byte blocks    

  The quick and easy method to convert between size units

 There is an extremely fast and easy way to do any of these conversions.   With this method the only number you need to memorize is 1024.   
 The only other thing you need to know is the name/order of the sizes (kilobyte, megabyte, gigabyte, terabyte).   To convert smaller units to larger units (i.e. take bytes and convert to kilobytes, megabytes, gigabytes, or terabytes) you simply divide the original number by 1,024 for each unit size along the way to the final desired unit.   
 For example, if you wanted to convert 110,214,321,212 bytes to megabytes, you would divide by 1,024 (to first covert to KB), and then divide by 1,024 again (to end up in MB).   If you wanted to convert to gigabytes, you would divide by 1,024 three times (once to get to KB, once to get to MB, and then once to end up in GB).

 To convert larger units to smaller units (i.e. take a number of gigabytes and convert it down in to megabytes, kilobytes, or bytes) you simply mulitply the original number by 1,024 for each unit size along the way to the final desired unit.   For example, if you want to convert 384 megabytes to bytes, you would simply multiply it by 1,024 two times (first time to convert to KB, and the second time to end up in bytes).   If you wanted to convert 14 terabytes to the number of bytes, you would multiply 14 by 1,024 four times (first to convert to GB, then to MB, then to KB, and then to bytes).
