Frequently Asked Questions

Verified answers and formulas for converting terabits per second to gigabytes per second.

How many gigabytes per second are in 1 terabit per second?

There are 125 gigabytes per second (GB/s) in 1 terabit per second (Tbps). Conversely, 1 gigabyte per second equals 0.008 terabits per second.

How do you convert terabits per second to gigabytes per second?

To convert terabits per second (Tbps) to gigabytes per second (GB/s), use the formula: GB/s = Tbps × 125. Multiply the terabit per second value by 125. For example, 10 Tbps equals 1250 GB/s.

How do I convert back from gigabytes per second to terabits per second?

To convert in the reverse direction from gigabytes per second (GB/s) to terabits per second (Tbps), use the inverse formula: Tbps = GB/s / 125. Divide the gigabyte per second value by 125 (1 GB/s = 0.008 Tbps).

What is the difference between terabit per second (Tbps) and gigabyte per second (GB/s)?

Both terabit per second and gigabyte per second measure data transfer rate. Terabit per Second (Tbps) is a unit in the Data Transfer Rate measurement category. It is widely used in fiber optic & datacenter backbones. Relative to the data transfer rate base unit, 1 Tbps equals 1000000000000 Bits per Second (bps). Gigabyte per Second (GB/s) is a unit in the Data Transfer Rate measurement category. It is widely used in gigabytes per second. Relative to the data transfer rate base unit, 1 GB/s equals 8000000000 Bits per Second (bps).

Why is my download speed slower than my internet plan in Mbps?

Internet plans are sold in megabits (Mbps), while files download in megabytes (MB/s). Because 8 bits equal 1 byte, a 100 Mbps connection downloads at maximum ~12.5 MB/s.
