units of measure

Drive capacities as measured in terms of bytes of information or data stored. The number of bytes that can be stored on today’s drives and storage media ranges from 1 MB (megabyte) to several hundred GB (gigabytes). KB = One kilobyte is equal to 10 to the 3rd power (10^3 bytes) or 1000 bytes. MB = One megabyte is equal to 10 to the 6th power (10^6) or 1,000,000 bytes. GB = One gigabyte is equal to 10 to the 9th power (10^9) or 1,000,000,000 bytes. One gigabyte is equal to a 1000 megabytes or a 1,000,000 kilobytes.TB = One terabyte is equal to 10 to the 12th power (10^12) or 1,000,000,000,000. A terabyte is equal to a million, million bytes or 1,000 gigabytes.PB = One petabyte is equal to 10 to the 15th power (10^15) or 1,000,000,000,000,000,000 bytes. One petabyte is equal to a 1000 terabytes.
