Overview

Engineering reference data for Surface Roughness Abrasive Grain Size in miscellaneous.

$y = x \cdot k$

Multiply by conversion factor.

$y = y_1 + \frac{(x - x_1)(y_2 - y_1)}{x_2 - x_1}$

Estimate between two known points.

$p = \frac{\text{part}}{\text{whole}} \times 100\%$

Part as fraction of whole.
