# What is 1 petaFLOPS equal to?

## What is FLOPS?

The performance capabilities of supercomputers are expressed using a standard rate for indicating the number of floating-point arithmetic calculations systems can perform on a per-second basis.

The rate, **fl**oating-point **o**perations **p**er **s**econd, is abbreviated as **FLOPS**.

## The orders of magnitude in computer performance

### GigaFLOPS

1 gigaFLOPS (GFLOPS) = 10^{9} FLOPS

### TeraFLOPS

1 teraFLOPS (TFLOPS) = 10^{12} FLOPS = one trillion FLOPS

### PetaFLOPS

1 petaFLOPS (PFLOPS) = 10^{15} FLOPS = one thousand trillion (one quadrillion) FLOPS

### ExaFLOPS

1 exaFLOPS (EFLOPS) = 10^{18} FLOPS

### ZettaFLOPS

1 zettaFLOPS (ZFLOPS) = 10^{21} FLOPS

### YottaFLOPS

1 yottaFLOPS (YFLOPS) = 10^{24} FLOPS
