About

ErrorGerm is an open-source web app that aims to ease the calculation of uncertainty propagation in learning environments such as physics labs in college. It allows entering scalar values and assigning them to a variable along with its uncertainty already calculated, or entering individual measures to calculate uncertainty. ErrorGerm can also export and import a session for later usage.

Built with

ErrorGerm makes use of math.js and MathJax

A note about precision

ErrorGerm uses numbers with a limited precision of 64 bits, that’s about 16 digits. So it has been decided to include up to 15 significant figures which are only for display purposes, all calculations are made with the available digits. You can read more about round-off errors here
