Formula
Given Gb gigabits:
- Bits = Gb × 109
- Bytes = Bits ÷ 8
- GB (decimal) = Bytes ÷ 109
- GiB (binary) = Bytes ÷ 230
Equivalently, GB = Gb ÷ 8 and GiB = Gb × 109 ÷ (8 × 230).
FAQs
GB uses powers of ten while GiB uses powers of two. Many operating systems show storage in GiB while network equipment often uses GB based on decimal powers.
Backbone links and carrier grade plans are commonly quoted in gigabits per second. Starting from gigabits avoids repeated scaling before conversion to storage oriented units.
Pick GB for decimal if you work with data sheets using powers of ten. Pick GiB for binary if you want values matching many operating system disk and memory displays.
Yes in decimal mode one GB equals eight Gb because one Byte equals eight bits. Exact equality differs in binary mode because GiB is based on 2 to the 30 Bytes.
Some sites mix binary and decimal prefixes. Ensure you compare GB with GB or GiB with GiB and check rounding precision to match methods.
Yes use the Copy shareable link button. It captures inputs in the URL so you can save the link or share it in documentation and support tickets.
Yes calculations use floating point arithmetic and support very large inputs. For critical audits also consider using exact big integer arithmetic in a separate verification tool.
