About PIER: Ohm's Law Calculator
A beautiful, quick and accurate calculator to help find the voltage, current, resistance, and power. Quick and easy to use. Interact with the ohm's law wheel to help encourage you to learn/remember the formulas of the wheel.
Click on a formula and enter in the two variables to find the answer. Not only will it show the answer in the bottom left, but it will also show the fourth variable in the top left.
Answers are transposed to a (easier to read) simplified value. When in need for a precise answer, simply click on one of the answers and the precise value will display with the ability to copy that value or the simplified value. Paste that value anywhere throughout your device that allows pasting.
•
The Metric Toolbar: Quickly enter in a value and change it's metric prefix without having to add a ton of 0's.
