Converters

Converter for data storage units

Convert data size between bytes, KB, MB, GB and TB with base 1024 or base 1000; every unit go show side by side.

Choices for this device

Na only the units wey you choose this browser go remember. E no save numbers or other inputs. E go use them for new examples wey you open alone; shared links and workspace cards go keep their own choices.

Unit	Value wey e get

All five units dey describe the same amount of data for the base wey you choose. If you change the base, every row go change.

Formula

Bytes = value × base^{source level}; target value = bytes ÷ base^{target level}, where levels na B=0, KB=1, MB=2, GB=3, TB=4.

Unit	Level	Bytes for base 1024	Bytes for base 1000
B	0	1	1
KB	1	1,024	1,000
MB	2	1,048,576	1,000,000
GB	3	1,073,741,824	1,000,000,000
TB	4	1,099,511,627,776	1,000,000,000,000

Strictly, KiB/MiB/GiB na base-1024 units and KB/MB/GB na base-1000 SI units. In practice many operating systems label base-1024 sizes as KB/MB/GB; this page follow that common labelling and let you switch base explicitly instead of hiding difference.

Example wey show the calculation

1 GB at base 1024 = 1 × 1024 = 1,024 MB, = 1,024 × 1,024 = 1,048,576 KB, = 1,073,741,824 bytes. Same 1 GB at base 1000 = 1,000 MB exactly. 2.5 TB drive at base 1024 na 2.5 × 1,024 = 2,560 GB.

Where e fit work and limits

We no accept negative sizes. The displayed values dey round to 6 decimal places, but we no round the calculation underneath. We no model formatted drive capacity, filesystem overhead or the KiB-vs-KB naming difference; this page only dey convert the number wey you enter.

Questions wey people dey ask often

Make I use base 1024 abi 1000?

Use 1000 for SI or manufacturer specifications: a drive wey dem sell as 1 TB usually mean 10^12 bytes. Use 1024 for sizes wey many operating systems report. If you no sure, check your source; the gap fit reach about 10% for TB sizes.

Wetin be difference between GB and GiB?

GiB unambiguously base 1024 (1 GiB = 1,073,741,824 bytes); GB na SI base-1000 unit. Many tools write GB when they mean GiB, na why this page make base explicit choice.

Why my 1 TB drive dey show less than 1 TB?

Part of the reason na this base difference: 10^12 bytes = 931.32 GiB for base 1024. Filesystem overhead dey account for the remaining difference.

How many MB dey inside one GB?

1,024 MB at base 1024, or 1,000 MB at base 1000 — answer depend on base, so always state am.

This tool fit handle bits?

No — na only bytes. 1 byte = 8 bits; first convert bits to bytes (divide by 8), then enter dat value.
