Gigabits to Gigabytes Converter

Convert decimal gigabits to decimal gigabytes; the shared decimal giga factor cancels, leaving 8 gigabits per gigabyte.

Gigabits to Gigabytes Converter: 1 gigabit = 0.125 gigabytes. To convert any amount, multiply the number of gigabits by 0.125. TOEA calculates with the full stored factor (gigabytes = gigabits ÷ 8 (decimal giga = 1000000000)) and keeps the calculation in your browser.
