Bits to Gigabytes formula

One bit is 1.25 × 10⁻¹⁰ gigabytes, so GB = b × 1.25 × 10⁻¹⁰. For the reverse, multiply gigabytes by 8,000,000,000, or use the Gigabytes to Bits converter.

Kilobytes, megabytes, gigabytes and terabytes here are decimal, as on drive labels: 1 kB = 1,000 bytes, 1 MB = 1,000 kB and 1 GB = 1,000 MB. Memory sizes and Windows count in binary units instead, where 1 KiB = 1,024 bytes, 1 MiB = 1,024 KiB and 1 GiB = 1,024 MiB, which is why a 1 TB drive shows as about 931 GiB. To switch between the two, use the gibibytes to gigabytes converter or the byte converter guide.

Bits to Gigabytes in Notes Calculator

Notes Calculator is a notepad that does math. Write 100 bits to GB on any line and the answer appears beside it. Change the number and the result follows. The same works with in and as, and with values stored in variables, so a whole estimate can mix bits and gigabytes without a separate converter.

See the unit conversion docs for mixing units in one expression, or open the free web app and try it.

Notes Calculator is a notepad calculator for the web and a calculator app for Mac, Windows, Linux, iOS and Android.
