How Do You Convert Rms To Peak Voltage?
It is common in electrical engineering problems to have to calculate the peak voltage from the RMS value of the sine wave. RMS is the root mean square. Follow the steps below to convert the RMS value to peak voltage or peak to peak voltage. Remember that the peak voltage is one half of the peak to peak voltage. Write the RMS value on a piece of paper. Multiply the RMS value times the constant of 1.414. This is the same as two times the square root of 2. The answer will be the peak voltage. To use your calculator to solve the problem, find the square root of 2 with your calculator. Multiply the number in step 3 by 2. Then multiply this answer by the RMS value to get the peak voltage. To convert from peak voltage to the RMS value, divide the peak voltage by 1.414 to get the RMS value.
