US vs UK Ratios

In the US, one cup of self-rising flour is typically made from one cup of all-purpose flour plus two teaspoons of baking powder and one quarter teaspoon of salt. UK self-rising flour uses the same leavening but leaves out added salt because many UK recipes assume unsalted butter.

$$\text{AP flour (cups)} = \dfrac{\text{desired self-rising cups}}{1 + \frac{48}{625} + \frac{3}{250}} \quad \text{(US)}$$
