Method and formula

Volumedot=π×(d2)2×hMassdot=Vdot×Density(g/cc)Dots/m2=1Pitch2GSM=Mdot×Dots/m2\begin{aligned} Volume_{\text{dot}} &= \pi \times \left(\frac{d}{2}\right)^2 \times h \\[0.5em] Mass_{\text{dot}} &= V_{\text{dot}} \times \text{Density(g/cc)} \\[0.5em] \text{Dots/m}^2 &= \frac{1}{\text{Pitch}^2} \\[0.5em] \text{GSM} &= M_{\text{dot}} \times \text{Dots/m}^2 \end{aligned}
