Type B Uncertainty Calculator. Type B Uncertainty Calculator is a stand-alone a tool for estimating uncertainties in cases were we may not have a sample of measurements to work from. In these cases, we need to calculate measurement uncertainty using our technical experience and knowledge. To learn more about why uncertainty exists and how to propagate it through equations, check out the guide! This calculator treats all measurements as normal distributions that are independent from each other.

This is common practice and often works well. Uncertainty in our measurements with real numbers is inevitable. The most common source of uncertainty are our measurement tools.

It calculates uncertainties two ways: most probable uncertainty , also called standard error or uncorrelated uncertainty , which is used when errors are independent; maximum uncertainty , also called maximum error or correlated uncertainty , which is used when they are not.

There are a couple of radio buttons to choose which type of uncertainty you want to use. Why is there no equals sign? This calculator operates in what is known as postfix mode. That means you input your values for X and Y first, and then you choose what you want to do with them.
