How to convert gigabits per second to bytes per second
A byte per second is 8 bits per second. Decimal Mbps and binary Mibit/s differ. These rates exclude protocol overhead; real transfer time also depends on throughput and latency.
Use x for the value in Gbit/s, b for the intermediate value in bit/s, and y for the result in B/s.
B/s = Gbit/s × 1000000000 ÷ 8
Worked examples
10 Gbit/s ≈ 1250000000 B/s
Step 1: (10 × 1000000000) ≈ 10000000000 bit/s.
Step 2: 10000000000 ÷ 8 ≈ 1250000000 B/s.20 Gbit/s ≈ 2500000000 B/s
Step 1: (20 × 1000000000) ≈ 20000000000 bit/s.
Step 2: 20000000000 ÷ 8 ≈ 2500000000 B/s.
Results are rounded to 12 significant digits. Converting units does not increase the precision of the original measurement. Very large or small values outside JavaScript’s finite numeric range are rejected.
About Gigabits per second
Gigabits per second (Gbit/s) measures data transfer under the conventions above. The base value in bit/s is (x × 1000000000), where x is the numerical value in Gbit/s. Factors shown here are rounded for display; calculations use the stored factor.
About Bytes per second
