# 6 Best Free Online EMF Calculator Websites

Here is a list of the best free online EMF calculator websites. EMF stands for Electromotive Force. EMF is an electric pressure in the circuit that is responsible for generating current. It is measured in Volts. There are different ways to measure the EMF in different systems. For example, in a galvanic (voltaic) cell, EMF is simply the electrical potential of the electrodes. With different formulas, you can measure the EMF of a circuit, transformer, etc.

This post covers 6 free websites that offer online EMF calculators. You can visit these websites and use the calculators right away. There is no need for any type of sign-in or anything. Then you can simply put the required values and get the value of EMF. I briefly covered each website along with the process of calculation and highlights. I also provided a direct link to each calculator. You can check out the post to know more about these calculators. Then maybe you can pick one as per your needs.

## My Favorite Online EMF Calculator

OmniCalculator is my favorite website on this list to calculate EMF online. This particular calculator estimates the electromotive force of any galvanic cell. It is quite simple and straightforward to use and gives the EMF in volts with options to convert to other units as well.
