The origins of the RPE scale can be traced back to the pioneering work of Swedish scientist Gunnar Borg, who developed the Borg Rating of Perceived Exertion scale in the 1960s. Borg's original scale ranged from 6 to 20, a structure intended to roughly align with the typical range of heart rates (60 to 200 beats per minute) seen during exercise. The Borg scale has since evolved into a more simplified 0-10 scale, calculator rpe which is commonly used in modern fitness settings for its clarity and ease of use. The revised scale allows individuals to subjectively rate their effort on a scale of 0 (rest) to 10 (maximum effort). For example, light activities such as casual walking may register around 2-3 on the scale, while sprinting at maximum capacity may rate as a 10.
