Byte Conversions • Convert MB to GB instantly

Kilobytes, gigabytes, and other byte multiple prefixes can be so confusing. To clear up confusion, let's start with what is a byte? A byte is a unit of digital information that normally consists of 8 bits. Which begs the question, what is a bit? A bit is the smallest digital unit, a binary digit. In our mind's eye we generally view bits as a 1 or a 0. That's fine and enough for now, so back to bytes. We now know that 8 bits makes one byte, and a byte is typically the encoding of a single digital character, like the letter "a". Obviously, modern computers can store and process huge amounts of data. Billions and trillions of bytes - amounts we can't wrap our heads around. Instantly get the answer to how many kb in 30 mb or any amount you're seeking using the byte conversion calculator. Simply select the starting multiple and enter the amount you want to convert. Then select the conversion multiple to get the answer. We default to the popular mb to gb conversion. Our conversion tool works with decimal kilobytes, not binary. So our converter considers 1 kB = 1,000 B. One last piece of great news - all DeeboData calculators work offline!
