Consider the following units: terabytes, gigabytes, kilobytes and megabytes.
Which unit contains the most bytes?
Which unit contains the least bytes?
Data can be represented using either:
Metric units - kilobytes \left( \text{kB} \right), megabytes \left( \text{MB} \right), gigabytes \left( \text{GB} \right), terabytes \left( \text{TB} \right).
Binary digital units - kibibytes \left( \text{KiB} \right), mebibytes \left( \text{MiB} \right), gibibytes \left( \text{GiB} \right), tebibytes \left( \text{TiB} \right).
Convert 670 \text{ KiB} to bytes.
Complete the missing values in the equivalence table, rounding your answers to two decimal places:

Convert 10\,050 \text{ B} to the following, correct to two decimal places:
Kilobytes
Kibibytes
Why are there fewer kibibytes than kilobytes for the same number of bytes?
Complete the following conversion table, leaving your answers as fractions where appropriate:
| \text{B} | \text{KiB} | \text{MiB} | \text{GiB} | |
|---|---|---|---|---|
| \text{1 B} | 1 | \dfrac{1}{1024} | \dfrac{1}{1024^3} | |
| \text{1 KiB} | 1 | \dfrac{1}{1024} | \dfrac{1}{1024^2} | |
| \text{1 MiB} | 1024^2 | 1024 | 1 | |
| \text{1 GiB} | 1024^3 | 1024 | 1 |
Convert the following to the indicated unit, correct to one decimal place:
4.895 \text{ kB} to \text{B}
0.3946 \text{ MB} to \text{B}
5\,700\,000 \text{ B} to \text{MB}
7100 \text{ GB} to \text{TB}
670 \text{ GB} + 890 \text{ GB} to \text{TB}
6.6 \text{ TB} + 700 \text{ GB} to \text{TB}
3.7 \text{ TB} - 800 \text{ GB} to \text{TB}
