Math conversions?

[Drucinda]

Is there anywhere to get basic math formulas/tutorials for converting cutting sizes like from HSTs to QSTs?
I use EQ7 and have a block pattern that calls for HSTs cut from a 5 1/2" square. I want to convert that to cutting into a QST so that I can use the method of sewing a 1/4" on all four sides prior to cutting.
