Computing scales

These are computing scales measured in floating point operations per second (FLOPS).

Deciscale (10−1)

 * 5×10−1 Average human mental calculation

Scale (100)

 * 1 Average human addition calculation

Decascale (101)

 * 5×101 Upper end of human perception

Hectoscale (102)

 * 2.2×102 Upper end of human throughput

Kiloscale (103)
