Hello Sidhant, The factor of 102 is used to convert mmWC into pascals because the formula for the static fan efficiency in SI units is;-. Static Fan Efficiency = Volume (m3/s) * Pressure gain (Pa) / Power input (W) * 100. But, if the pressure is measured in mmWC instead of Pascals and Power is expressed in kW, the formula can be derived as
