What this result means
This converts a stated peak-to-trough flatness across the plate measurement span into equivalent angular units. For rectangular plates, use the span to which the flatness specification applies.
Formula: angle = arctan (flatness ÷ measurement span). Flatness is converted from micrometres to millimetres before calculation.
