How to Calculate THD

I want to know about IEEE 519 Harmonics standards. And Formulas to calculate Total Harmonic Distortion (THD) for Voltage and Current according IEEE standards. Till now i am calculating by taking Square root of the ratio of the sum of the squares of the total harmonics to the fundamental harmonics.

And i am measuring the I THD and V THD by using fluke meter. I want to know how to calculate the THD as per IEEE standards.
