Formula (LaTeX) + variables + units
This section shows the formulas used by the calculator engine, plus variable definitions and units.
Formula (extracted LaTeX)
\[\text{Area}_{\text{room}} = L \times W\]
\text{Area}_{\text{room}} = L \times W
Formula (extracted LaTeX)
\[\text{Module}_{\text{eff}}^x = \text{module}_x + g, \quad \text{Module}_{\text{eff}}^y = \text{module}_y + g\]
\text{Module}_{\text{eff}}^x = \text{module}_x + g, \quad \text{Module}_{\text{eff}}^y = \text{module}_y + g
Formula (extracted LaTeX)
\[\text{Units}_{\text{net}} = \frac{\sum (L_i \cdot W_i)}{\text{Module}_{\text{eff}}^x \cdot \text{Module}_{\text{eff}}^y}\]
\text{Units}_{\text{net}} = \frac{\sum (L_i \cdot W_i)}{\text{Module}_{\text{eff}}^x \cdot \text{Module}_{\text{eff}}^y}
Formula (extracted LaTeX)
\[\text{Units}_{\text{final}} = \left\lceil \text{Units}_{\text{net}} \cdot (1 + w) \cdot p_f \right\rceil\]
\text{Units}_{\text{final}} = \left\lceil \text{Units}_{\text{net}} \cdot (1 + w) \cdot p_f \right\rceil
Formula (extracted text)
\[\text{Area}_{\text{room}} = L \times W\] \[\text{Module}_{\text{eff}}^x = \text{module}_x + g, \quad \text{Module}_{\text{eff}}^y = \text{module}_y + g\] \[\text{Units}_{\text{net}} = \frac{\sum (L_i \cdot W_i)}{\text{Module}_{\text{eff}}^x \cdot \text{Module}_{\text{eff}}^y}\] \[\text{Units}_{\text{final}} = \left\lceil \text{Units}_{\text{net}} \cdot (1 + w) \cdot p_f \right\rceil\] where \\ \(g\) = grout/joint width (converted to same units as module), \(w\) = waste fraction (e.g., 0.10), and \(p_f\) = pattern factor.
