Propagation of Error Calculator

Automatically calculate the Propagation of Error (or Propagation of Uncertainty) of any expression and easily copy to your Excel, Python or Latex Project! Click the HELP menu for further details.

1. Input your Expression (supports Excel and Python Syntax)

Expression Result:

2. Choose the Alias and Error for your variables. This can be their value, a custom name or an Excel cell!

3. Choose a formatting option (Python, Excel or Latex) and the error type (Absolute or Quadratic) and get your Propagation of Error Expression!

Expression Result:

"Absolute"

"Quadratic"

$\sum_{i=1}^n | \frac{\partial F}{\partial x_i}| \cdot \delta_i$

$\sqrt{ \sum_{i=1}^n (\frac{\partial F}{\partial x_i} \cdot \delta_i)^2}$

And that's it! You can now copy the result into your Project and continue your work!
