To give you a better idea of the amount of data each unit can store, here are a few examples:ġ GB = approx. The units of measurement displayed in the table are quite abstract. Instead, the conversion number 1,024 is used alongside existing terms mega, giga, and tera. Since the conversion number 1,024 is used in the system, 1 gibibyte = 1,024 mebibytes and 1 tebibyte = 1,024 gibibytes.Īlthough these measurement units are also recommended by the International Bureau of Weights and Measures (BIPM), they have yet to catch on. They are based on the SI prefixes but contain the intermediate syllable ‘bi’. The revised units of measurement are called binary prefixes or IEC prefixes. That is why the International Electrotechnical Commission (IEC) introduced new prefixes based on the power of 2. ![]() When you convert bytes using the number 1,000, deviations arise and as data quantities grow, these deviations also become ever larger making for imprecise measurements. The SI prefixes mega, giga, and tera originate from the decimal system, which is based on base 10 (10 x), since a total of ten digits are being used. However, this conversion has its pitfalls: Computers use the binary system (or dual system), which is based on only two digits and is therefore based on base 2 (2 x). ![]() ![]() According to the decimal system, 1,000 MB = 1 GB and 1,000 GB = 1 TB. Nearly as common as gigabytes are measurements in megabytes and terabytes. ![]()
