to 100. It can be used with the D scale to read square or
square root values. This scale is normally located at the
bottom area of the top rule. Various gauge marks are located on this scale at π, π/4, τ, and M (100/π) Formula: A = X² |

The AI scale is an inverse A scale, reversed
in direction from the A scale (reciprocal scale). Gauge marks are located at π and τ. Formula: AI = 1 / (X²) |
