Overview
When you perform calculations with measured values, the uncertainty (error) must be propagated to the result. This calculator uses the standard quadrature formula (assuming independent errors).

Pro Tips
Assumes uncertainties are independent and random (not systematic).

Fun Facts
"For Addition/Subtraction, absolute errors add in quadrature."
"For Multiplication/Division, relative errors add in quadrature."
