This page converts bits per second into gigabytes per second using the factor 1.250000000e-10, and shows the reverse figure alongside it. Both units measure how much data moves per second, which is why one number does the whole job.
One bit per second is the base unit of data rate. Network speeds are always quoted in bits, which is why a 100 Mbps line downloads at about 12 MB/s. Gigabytes per second is the scale of NVMe storage and memory buses rather than networks.
Bits and bytes. Network speeds are sold in bits per second and file transfers are reported in bytes per second, and there are eight bits to a byte, so a 100 Mbps line downloads at about 12 MB/s. A connection is not underperforming by a factor of eight; it is being measured in different units. Below the calculator there is a step table for the values people look up most, and a second table putting real how much data moves per second figures into gigabytes per second so the number you get has something to be compared against.
The formula
bits per second- The amount you are converting, in bits per second
1.25000000000e-10- The exact number of gigabytes per second in one bit per second
gigabytes per second- The converted result
How it works, step by step
- Enter the value in bits per second.
- It is multiplied by 1.25000000000e-10, the exact factor between the two units.
- The answer is shown in gigabytes per second, with the reverse conversion beneath it.
- Check the reference table if you want a figure of comparable size.
Worked examples
HD video stream: 8e+06 bit/s in gigabytes per second
At 8e+06 bit/s (hd video stream), the same quantity in gigabytes per second is 8e+06 × 1.25000e-10 = 0.001 GB/s. One bit per second is 1.25000e-10 gigabytes per second, so the numbers shrink as expected.
SD video stream: 3e+06 bit/s in gigabytes per second
Take sd video stream, roughly 3e+06 bit/s. The conversion is a single multiplication — 3e+06 × 1.25000e-10 — giving 0.000375 GB/s. Because the relationship is proportional, doubling the input doubles the answer to 0.00075 GB/s.
How to read your score
Frequently asked questions
How many gigabytes per second are in one bit per second?
Exactly 1.25000000000e-10. Every figure on this page is that one number multiplied by your input, so the only rounding is at the display step.
What is the formula to convert bits per second to gigabytes per second?
gigabytes per second = bits per second × 1.25000000000e-10. Reversed, bits per second = gigabytes per second ÷ 1.25000000000e-10, which is the same as multiplying by 8,000,000,000.
Which is the bigger unit, the bit per second or the gigabyte per second?
The gigabyte per second. One bit per second is only 1.25000e-10 of a gigabyte per second, so it takes 8e+09 bits per second to make one gigabyte per second.
What does this quantity actually measure?
Both units measure how much data moves per second. That is why a single factor is enough: there is no temperature offset and no material property involved, unlike conversions that cross between different quantities.
What is a bit per second?
One bit per second is the base unit of data rate. Network speeds are always quoted in bits, which is why a 100 Mbps line downloads at about 12 MB/s.
What is a gigabyte per second?
Gigabytes per second is the scale of NVMe storage and memory buses rather than networks.
Why does my answer differ from another converter?
Almost always because the other tool rounded the factor before multiplying. This page keeps full double precision through the calculation and rounds only for display, and it prints the factor it used so you can see where any difference came from.
