This triangular ruler is marked in full and 1/2 scale centimeters on one side, full and 1/2 scale inches on the other. Used 1/2 scale, this is probably the most popular charting tool. Think of it as a ruler that "lies to you". That is, when the ruler indicates 5", it is really measuring 2.5" - it eliminates all the math when converting full to half (or half to quarter scale).
