How to convert GiB to kB
kB = GiB × 1,073,741.824. The scale factor is the source-unit factor divided by the destination-unit factor.
Worked example
For a file size or storage capacity of 500 GiB converts to 536,870,912 kB.
- Start with 500 GiB.
- Multiply 500 by 1,073,741.824.
- Report 536,870,912 kB, rounded to the precision of your original measurement.
Check the reverse conversion
1 kB = 0.0000009313225746 GiB. Use the kilobyte to gibibyte converter to calculate in the opposite direction. This has its own formula and reference table.
Definitions that matter
A byte is eight bits. MB is not MiB, and GB is not GiB. Storage capacities are quantities; data-transfer rates such as Mbps add a time dimension and are not included here.
The base unit for this category is B. One GiB corresponds to 1,073,741,824 byte; one kB corresponds to 1,000 byte. These definitions explain the relationship rather than relying on a rounded display value.
Sources and precision
Definitions: NIST binary prefixes. Calculations use double precision; the tool defaults to a readable rounded result, while tables show up to ten significant digits. Displaying more digits does not increase the accuracy of the original measurement.
