What is the difference between 250MB and 2.5GB?

250mb is bigger I think and 2.5gb is smaller because it's 2.5x100=250 so it is smaller isen't it. :)

It isen't that 2.5gb is bigger because if you think of it

1024KB = 1MB

1024MB = 1GB

1024GB = 1TB

2.5GB x 1024 x 1024 = 2621440 KB

so

giga is 1000,000000. Thousand million.

and

2.5 GB = 2,500 MB

2.5 GB = 2,500,000 KB

2.5 GB = 2,500,000,000 Bytes

so both are right my answers
