Note that rounding errors may occur, so always check the results. Use this page to learn how to convert between kilobytes and bytes. Type in your own numbers in the form to convert the units! You can do the reverse unit conversion from byte to KB , or enter any two units below:.
A kilobyte is a unit of information or computer storage equal to bytes, assuming a binary system. This is not a standard SI definition, which would use kibibyte to represent bytes. The International System of Units SI defines the prefix kilo as ; per this definition, one kilobyte is bytes.
The internationally recommended unit symbol for the kilobyte is kB. The byte is a unit of digital information that most commonly consists of eight bits. Historically, the byte was the number of bits used to encode a single character of text in a computer and for this reason it is the smallest addressable unit of memory in many computer architectures.
Maybe you mean Kibibyte? How many bytes in 1 kilobyte? A flash memory card used in a camera might store 16 GB. How many fit on a 16 GB flash drive? You can buy 4 TB hard drives today, so we are beginning the time when this term comes in to common use.
Gigabyte used to be an exotic term too, until Moore's law made it common. Gigahertz - Speed, not Bytes One gigahertz is 1 billion cycles per second a megahertz is a million cycles per second.
Gigahertz is a measure of speed, very roughly the rate that at a CPU can do its simplest operation per second. Gigahertz does not precisely tell you how quickly a CPU gets work done, but it is roughly correlated. Higher gigahertz CPUs also tend to be more expensive to produce and they use more power and as a result give off more heat - a challenge for putting fast CPUs in small devices like phones. The ARM company is famous for producing chips that are very productive with minimal power and heat.
Basic plan: before adding measures X and Y, convert them to be in the same units. Bob has MB of data. Will it all fit on Alice's 4 GB thumb drive?
