FLOPS means floating point operations per second -- an approximate measure of a computer's processing speed.

• Megaflops means one million FLOPS, and
• Gigaflops means 1000 million FLOPS.
• teraflops means 10¹² FLOPS. The most powerful supercomputers have speeds measured in teraflops.
• Petaflops means 10¹⁵ FLOPS, or a million gigaflops.
• ZettaFLOP means 10²¹ FLOPS

FLOPS, like MIPS, are arguably not very useful as a benchmark for modern computers because there are many other factors in computer performance other than raw floating-point computation speed, such as interprocessor communication, cache coherence, and the memory hierarchy.

However, for purely mathematical calculations, such as analysis of data, the FLOPS measurement is effective.
