- 1 Gb = 0.125 GB
- 8 Gb = 1 GB
- 1000 Gb = 125 GB
Check the units before using the answer
Gigabits use a decimal prefix: one Gb equals 1,000,000,000 bits. Gigabytes use a decimal prefix: one GB equals 1,000,000,000 bytes.
This pair also changes the data unit. Keep bits and bytes separate: one byte contains 8 bits. A change from b to B is not just a change in capitalization.
Frequently asked questions
Why can the displayed result contain a decimal?
The destination unit may represent a larger amount of data than the source unit. A fractional result is valid for a unit calculation; it does not mean that a file has been split or its storage allocation has changed.
How should I handle rounding?
Keep additional precision during intermediate calculations and round only the final value to suit your task. The formula above is exact; example values marked approximately are shortened for readability. A calculator display can also limit the digits shown.
Does this calculate transfer time?
No. These units describe data quantity. Transfer-time calculations also require a data rate and matching time units.
