1MB = 8Mb (megabits)

1GB = 8Gb (gigabits)

32768B = 2¹⁵B = 2¹⁵*2³ = 2¹⁸b

2¹⁸b / 2¹⁰ = 2⁸Kb (kilobits)

2⁸Kb / 2¹⁰ = 2^-2Mb (megabits)

2^-2Mb / 2¹⁰ = 2^-12 Gb (gigabits)

0,25TB = 2Tb = 2¹*2¹⁰ = 2¹¹Gb

2048GB = 2¹¹GB = 2¹¹*2¹⁰*2¹⁰ = 2³¹KB

Exercise 1. How long will it take to download a 1GB file with a 300Mb/s constant link?

1GB = 1024MB = 8192Mb

8192/300 = 27,3s

Exercise 2. Can we save 250 800KB files on a 32GB pendrive?

32GB = 2⁵*2¹⁰ = 2¹⁵MB*2¹⁰ = 2²⁵KB = 33554432KB

33554432/800 ≈ 41943

Answer: Yes, we can.
