Zettabits per second (Zbit/s)
Terabits per second (Tbit/s)

Conversion Formula

Tbit/s = Zbit/s × 1000000000

About Zettabits per second

Zettabit per second (Zbit/s) = 10²¹ bit/s (SI). Entirely theoretical. The entire global internet traffic in all of 2024 (≈40 Zbit) could be transferred in ≈40 seconds at 1 Zbit/s. The full electromagnetic spectrum (radio to gamma, ≈10³⁰ Hz bandwidth) at Shannon capacity still cannot sustain 1 Zbit/s with any known physical medium. 1 Zbit/s = 10²¹ bit/s = 125 EB/s.

About Terabits per second

Terabit per second (Tbit/s) = 10¹² bit/s (SI). Internet backbone scale: MAREA cable (2017) = 200 Tbit/s per fibre pair; 2Africa cable (2024) = 180 Tbit/s. DWDM: 100 wavelengths × 800 Gbit/s = 80 Tbit/s per fibre. H100 GPU HBM3 memory bandwidth = 3.35 Tbit/s per GPU. NTT lab record (2023): 1,200 Tbit/s over a single fibre. 1 Tbit/s = 10¹² bit/s = 125 GB/s.
