Storage units: bits and bytes — Computer worksheet

Remember

Multiply to go smaller — “to change a bigger unit into a smaller one, multiply”

1. Order from smallest to biggest: bit < byte < KB < MB < GB < TB.
2. 1 byte = 8 bits; 1 KB = 1024 bytes; 1 MB = 1024 KB; 1 GB = 1024 MB; 1 TB = 1024 GB.
3. To change big units into small units, multiply: 2 KB = 2 × 1024 = 2048 bytes.

Use it for: Class 3 computer lessons on memory units, comparing file sizes and checking how much a pen drive can hold.

Worked example: 💾 How many bytes are there in 2 KB? → 2048
