The Uncertainty in Addition and Subtraction calculator computes the uncertainty in addition and subtraction based on the experimental absolute uncertainty in three measurements.
INSTRUCTIONS: Enter the following:
(e1) This is the experimental absolute uncertainty of one measurement (unit-less).
(e2) This is the experimental absolute uncertainty of another measurement (unit-less).
(e3) This is the experimental absolute uncertainty of a third measurement (unit-less).
Uncertainty in Addition and Subtraction (e4): The uncertainty is returned as a real number. However, this can be automatically converted to a percentage or decibels via the pull-down menu.
