What is the Root Mean Square (RMS) Calculator?

The Root Mean Square (RMS) Calculator computes the RMS of a set of numbers, which is a measure of the magnitude of values regardless of their sign. RMS is widely used in physics, engineering, and statistics to calculate the effective value of a varying quantity. The RMS is calculated by squaring each number, finding the mean of these squares, and then taking the square root of that mean. This calculator also provides a step-by-step table showing each value, its square, the mean of squares, and the resulting RMS.

How to Use:

1. Enter Values: Input your numeric values as a comma-separated list, e.g., 3, 4, 5, 6, 7.
2. Click “Calculate”: The calculator squares each value, computes the mean of the squares, and then finds the square root of this mean.
3. View Results: The output shows the total number of values, the mean of squares, the RMS value, and a detailed table showing each value and its square for transparency.
