A fudge factor is an ad hoc quantity or element introduced into a calculation, formula or model in order to make it fit observations or expectations. Also known as a correction coefficient, which is defined by \kappa_\text{c} = \frac{\text{experimental value}}{\text{theoretical value}}. Examples include Einstein's cosmological constant, dark energy, the initial proposals of dark matter and inflation.
