mobile phone


A byte (B) is a unit of digital information.


Here are the conversions

1,000 B (Bytes) = 1 KB (Kilobytes)

1,000,000 B = 1 MB (Megabyte)


1,000,000,000 B = 1 GB (Gigabyte)


Let's have a look at a typical question. 



Convert 9 GB to B



1,000,000,000 B = 1 GB (Gigabyte)


There are 1 billion bytes in a GB

So, 9 GB = 9 x billion B

= 9,000,000,000 B


How do you feel about these conversions? Are you ready to have a go at some questions?
