Borg scale

either of two scales for measuring intensity of sensation and experience, enabling comparisons across people and across tasks. The RPE scale (rating of perceived exertion) is used specifically for measuring perceived effort in physical work. The CR10 scale (categorical rating with a scale from 1 to 10) is a general method that measures the magnitude of different sensations, including pain, loudness and noise, and brightness. These scales are used in psychophysics as well as in fitness training, ergonomics, and rehabilitation. [Gunnar Borg, 20th-century Swedish psychologist]
