(March 2010). The root mean square (abbreviated RMS or rms), also known as the quadratic mean, in statistics is a statistical measure defined as the square root of the mean of the squares of a sample.n the case of a set of n values, the RMS. The corresponding formula for a continuous function (or waveform) f(t) defined over the interval is. and the RMS for a function over all time is. The RMS over all time of a periodic function is equal to the RMS of one period of the function.
RMS and Ra are based on different methods of calculating the roughness. Both are done with a profilometer, but the profilometer calculates the roughness differently for Ra and RMS. Ra is the arithmetic average of surface heights measured across a surface. Simply average the height across the microscopic peaks and valleys. Ra and RMS are both representations of surface roughness, but each is calculated differently. Ra is calculated as the Roughness Average of a surfaces measured microscopic peaks and valleys.
