## 有效值计算器 Description
应该如何计算有效值（RMS）？ 100V有效值的幅度是多少？
在这种情况下，您在每次检查计算公式时都具有计算有效值的经验吗？

这个程序可以快速转换交流波形的有效值和幅度。

转换单位有4种：有效值（RMS），平均值，峰值(Peak)和峰峰值(Peak to Peak)。
通过输入交流波形的幅度或有效值并选择输入值的单位，将显示转换为4种单位的值。


---English---

How should the effective value be calculated? What is the amplitude of the effective value of 100V?
In such a case, do you have any experience of calculating the effective value while checking the calculation formula every time?

This app can quickly convert the effective value and amplitude of AC waveforms.

There are 4 types of conversion units: rms value, average value, amplitude, and Peak to Peak Amplitude.
By inputting the amplitude or effective value of the AC waveform and selecting the unit of the input value, the value converted into 4 types of units will be displayed.
