Hello Cruss! Welcome to the Cove!:bigwave:

The short answer to your question is: sure you can!

Here is a site that has several tools for calculating uncertainty:

Here is a thread that I have an Excel uncertainty calculator. I think I got it from here (The Cove), but I don't recall:

If you desire, you might want to pop over to the Post Attachment List, and search for others; I think there are more posted here.:)

Hope that helps!:bigwave:

thank you Brad, i`ll check the links

The yellow cells are open for entering data. The rest of the calculation is locked to protect any formulas.

This is not Excel, but is a free , nice, and understandable Uncertainty Calculator;
go to isgmax.com/sidekick_details.htm

The program name is Uncertainty Sidekick

There is a nice manual and help pop-ups to advise you of what to plug in where!
