# Closed Surface Electric Field Calculator

getcalc.com's **Gauss's Law Calculator** is an online physics tool to numerically calculate the magnitude of closed surface electric field due to different charge distributions, in both US customary & metric (SI) units.

## Definition & Formula

**Gauss's Law**, also known as Gauss's flux theorem, states that the the total flux of an electric field through a closed surface is directly proportional to the enclosed electric charge.
